A Series on the End of the Global Order

PROLOGUE

Before the Map Dissolves

The most dangerous moment is not when the system breaks. It is the long moment before, when everyone can see the cracks and most choose, for entirely rational reasons, to look away.

I. The Problem of Seeing Clearly

There is a particular kind of knowledge that arrives too late. Not because the information was unavailable, but because the information was unbearable, and so it was processed in ways that preserved the comfort of those receiving it. The data was acknowledged, catalogued, discussed in the appropriate forums, and then set aside in favor of the more pressing business of the day. This is not ignorance. It is something more troubling than ignorance — a civilized, institutionalized, professionally respectable form of not-quite-knowing that allows the machinery to keep running until the morning it cannot.

The historians of the First World War have spent a century accounting for precisely this phenomenon. The diplomatic records of the years before 1914 are full of intelligent, well-informed people registering alarm — noting the fragility of the alliance system, the combustibility of Balkan nationalism, the accelerating arms competition, the domestic political pressures forcing governments toward confrontation rather than accommodation. The alarm was registered. The system continued. July 1914 arrived as a shock to people who had, in a certain sense, been expecting it for years.

This series of essays begins from the conviction that we are living through a comparable moment: a period in which the structural conditions for major systemic disruption are clearly visible to those willing to look directly at them, and in which the prevailing institutional response is the same combination of accurate diagnosis and civilized evasion that characterized the decades before the last great transition. We are not sleepwalking, exactly. We are walking with our eyes open toward something we have collectively decided it is not yet necessary to fully confront.

That decision will not hold indefinitely. The forces reshaping the international system are not waiting for consensus about how to describe them. They are operating on their own timescales, generating their own dynamics, producing outcomes that are indifferent to the comfort of those who analyze them from positions of relative safety. The purpose of this series is to look at those forces directly — to trace their genealogy, to examine their interactions, to take seriously the moral weight of what they portend — without the analgesic evasions that normally make such material manageable for both writer and reader.

That is a harder task than it sounds. Evasion is not always cowardice. Sometimes it is professionalism — the appropriate bracketing of emotional response that allows analytical clarity. Sometimes it is genuine uncertainty about what, if anything, responsible analysis should recommend in the face of forces too large and too complex to be redirected by individual will. And sometimes it is simply the human preference for maintaining, as long as possible, a world in which the things one values still appear to be holding. These are not contemptible impulses. But they are insufficient for the moment we are in.

II. What an Order Actually Is

The word “order,” applied to international politics, carries a false suggestion of peace. The post-1945 order was not peaceful. It contained the Korean War, the Vietnam War, the Cambodian genocide, the Iran-Iraq War, the Soviet war in Afghanistan, the Rwandan genocide, the Balkan wars, and dozens of other conflicts that killed millions of people. The Cold War itself was a global confrontation that came within hours of nuclear exchange on at least two occasions. To call this period an “order” is not to claim that it was humane.

What an order actually is, in the technical sense used by historians and political scientists, is something considerably less morally satisfying: a stable arrangement of organized power, in which the dominant actors have reached sufficient agreement about the basic rules of their competition that the competition itself does not destroy the framework within which it takes place. An order does not require that violence be eliminated. It requires only that violence be bounded — that the major powers exercise sufficient restraint to prevent their conflicts from escalating into total systemic warfare. It is, at its core, a managed competition, not a peace.

This distinction matters enormously for understanding what it means when an order ends. The end of an order does not mean the end of conflict. It means the end of the specific framework of rules, institutions, and power arrangements within which conflict was previously contained. When that framework dissolves, the conflicts do not dissolve with it. They continue — but now without the constraints that previously kept them from reaching their maximum destructive potential. The competition becomes unmanaged. The boundaries dissolve. And the actors, uncertain about what rules now apply and who will enforce them, begin to act in ways calibrated for the worst case rather than the best.

The consequence, historically, is a period of dramatically elevated violence. The dissolution of the Westphalian framework after the French Revolution and Napoleon produced the most intensive military mobilization Europe had yet seen. The dissolution of the Vienna Concert framework after 1914 produced the two most destructive wars in human history, separated by an interwar period of political collapse, economic catastrophe, and ideological radicalization. These were not coincidences. They were the predictable consequence of managed competition becoming unmanaged — of the framework being dissolved before a successor framework was available to replace it.

It is against this backdrop that the phrase “the end of the post-1945 order” should be understood. What is ending is not merely U.S.A. geopolitical primacy, or the specific institutions constructed after the Second World War, or the particular norms of sovereignty and non-interference that governed (however imperfectly) the postwar international system. What is ending is the set of constraints that has, for eight decades, kept great-power competition below the threshold of direct military confrontation. The question of what will replace those constraints — whether anything will replace them quickly enough to prevent a period of unmanaged competition — is the central question of the coming decades. This series is, in its entirety, an attempt to think rigorously about that question.

III. The Accounting We Avoid

There is a conventional way to write about systemic transitions in international politics. You describe the structural forces — the shifting power distributions, the institutional failures, the technological disruptions, the demographic pressures. You trace the historical precedents. You identify the possible trajectories. You conclude with a careful assessment of risks and opportunities, acknowledge the uncertainty, and recommend continued attention to the relevant indicators. This is not dishonest. It is, in most professional contexts, exactly the right way to proceed.

What it omits is the thing that makes the topic worth taking seriously in the first place: the bodies.

The transition from the nineteenth-century order to the post-1945 system did not merely “reorganize the international distribution of power.” It killed, conservatively, one hundred million people between 1914 and 1945 — in trench warfare and aerial bombardment, in deliberately engineered famines and industrialized genocide, in the political violence of revolutionary states and the casual brutality of colonial administration, in the diseases and displacements that follow catastrophic social breakdown. These deaths were not incidental. They were structurally connected to the specific failure modes of the transitional period: the collapse of legitimating frameworks, the radicalization of political movements, the willingness of states to mobilize the full productive capacity of industrial civilization for the purpose of mass killing.

This accounting is not made here for rhetorical effect — to produce a shock of recognition that dissipates as quickly as it arrives. It is made because any analysis of the current systemic transition that does not foreground the question of human cost is, in a precise sense, incomplete. The purpose of understanding how orders collapse and reform is not intellectual satisfaction. It is the possibility, however partial, of reducing the suffering that transitions characteristically produce. If that purpose is lost — if the analysis becomes an end in itself, a technical exercise conducted at comfortable distance from its human stakes — then the analysis has failed at the most important level, regardless of its structural elegance.

There will be suffering in the transition currently underway. There already is. The wars in Ukraine and Gaza, the collapse of state authority across the Sahel, the humanitarian catastrophes in Yemen and Sudan, the displacement of tens of millions of people by a combination of conflict, climate stress, and economic desperation — these are not preliminary events preceding the real crisis. They are the crisis, already in progress, already generating its costs in human terms. The question is not whether suffering will accompany the transition but how much, of what kinds, distributed across which populations, and whether any of it could have been prevented by clearer thinking and braver political choices made earlier.

One of the recurring discoveries of historical research on major systemic transitions is how much of the suffering was not, in any meaningful sense, inevitable. The specific peace settlement after the First World War that generated the conditions for the Second was the product of particular political choices made by particular people operating under particular constraints — choices that could, in principle, have been made differently. The specific failure of democratic institutions in Germany and Italy in the 1930s was shaped by economic policies that could have been designed otherwise. The specific decisions that produced the Holocaust were made by a relatively small number of people acting through specific institutional structures. None of this is to say that the transition could have been cost-free. But the difference between the actual cost and the minimum possible cost is enormous — measured in the tens of millions — and it was produced by failures of political imagination and moral seriousness at critical junctures that were recognizable as critical at the time.

The same will be true of the current transition. When historians reconstruct it from the other side, they will identify the junctures, trace the choices, and note — with whatever mixture of grief and clinical detachment historians manage — the distance between what happened and what was possible. This series is written from the conviction that some of that future accounting can be done now, while the junctures are still open, and that doing it honestly is not a counsel of despair but the precondition of whatever responsible action remains available.

IV. The Forces This Series Examines

Every era of systemic transition has its specific forces — the particular combination of pressures, actors, and dynamics that give the transition its distinctive character. The current transition is not a simple replay of 1914–1945. It has its own profile of drivers, its own specific dangers and possibilities, and its own set of actors whose interactions will determine the shape of whatever comes next. Three clusters of forces will receive particular attention in this series.

The first is the structural redistribution of global power — the shift from the U.S.-led unipolar moment to a genuinely multipolar configuration in which multiple centers of economic, military, and political authority compete without any single dominant force capable of setting and enforcing the basic rules of the system. This shift is not merely about the relative decline of the United States and the relative rise of China. It is about the emergence of a world in which the Global South — the majority of the world’s population, carrying the accumulated grievances of colonialism and the distortions of externally imposed modernization — is increasingly refusing the subordinate role assigned to it by the institutions designed by others. Any international order that fails to genuinely incorporate these voices and interests will face a legitimacy deficit that no amount of institutional sophistication can overcome.

The second is the phenomenon of political Islam — examined here not as a security problem to be managed, not as an irrational residue of pre-modern consciousness, but as a civilizational force carrying genuine intellectual and political resources that the secular frameworks of Western social science have consistently failed to adequately describe. The Iranian Revolution of 1979, the mobilization of the Afghan mujahideen, the September 2001 attacks, the Arab Spring and its aftermath, the return of the Taliban, the proliferation of Islamic political movements across Africa, the Middle East, and South Asia — these are not disconnected episodes. They are expressions of a single underlying dynamic: the search, within Muslim-majority societies, for forms of political organization that are simultaneously modern and authentically Islamic, that do not require the abandonment of a comprehensive divine framework in favor of the secular social contract. This search will continue. Its outcomes will shape the political landscape of the coming decades in ways that no geopolitical analysis can responsibly ignore.

The third is the emergence of hybrid political-economic-cultural systems — configurations that combine elements of liberal institutional design, authoritarian governance, market economics, technological architecture, and ethno-religious identity in ways that resist the conventional categories of political science. China’s party-state capitalism, Turkey’s Islamic democracy, India’s majoritarian constitutionalism, Russia’s Orthodox nationalist Bonapartism — these are not transitional forms on the way to eventual liberal convergence. They are mature political products, generated by specific histories encountering shared challenges, and they are increasingly demonstrating their capacity to compete effectively with the liberal democratic model on multiple dimensions simultaneously. The interaction between these hybrid systems and the transnational forces of political Islam, demographic pressure, climate disruption, and technological competition will produce the specific contours of the next international order.

Cutting across all three of these clusters is the question of technology — and specifically of artificial intelligence — as a force multiplier whose effects are neither inherently liberal nor inherently authoritarian but will be shaped by the political and cultural contexts within which it develops. AI will amplify the advantages of states that lead in its development, provide new tools of surveillance and control to authoritarian governments, disrupt labor markets in ways that could generate new waves of political radicalization, and transform warfare in ways that current military doctrine is not adequately prepared for. Whether it will, on balance, stabilize or destabilize the transitional period is perhaps the most consequential open question of the near-term future.

V. On the Position of the Analyst

There is something uncomfortable about the act of geopolitical analysis that is rarely acknowledged in the literature. It is conducted, almost invariably, from a position of safety and comparative advantage — by people whose own lives are not, in any immediate sense, at stake in the outcomes they are analyzing. The analyst in London or Washington or Beirut or Singapore sits with a screen and a library and thinks about forces that are, for millions of people, not abstract at all. This asymmetry is not disqualifying. But it is morally significant, and it ought to inflect the way analysis is conducted and presented.

Specifically, it ought to create a persistent discomfort with the aestheticization of catastrophe — the tendency to find a certain cold beauty in the large-scale movements of historical forces, to write about systemic transitions with the intellectual pleasure that structural elegance produces, in ways that quietly background the human experience of those transitions in favor of the analytical elegance of describing them. This tendency is not unique to geopolitical writing. It runs through much of the historical literature on war, revolution, and imperial collapse. And it is a form of dishonesty — not of the data, but of the frame.

The frame that these essays attempt to maintain is one in which the structural analysis is always held accountable to its human stakes. The transition from the nineteenth-century order to the post-1945 system was not a fascinating reorganization of power that happened to involve some regrettable collateral suffering. It was, first and foremost, a catastrophe of enormous human magnitude that some surviving societies managed to build something functional from. The building-from-catastrophe part is important and worth analyzing carefully. But it does not redeem the catastrophe, and it does not license treating the catastrophe as a mere precondition for the interesting analytical material that follows.

This is not a call for sentimentality or for the subordination of analytical rigor to emotional response. Rigorous analysis is more useful, not less, when it is honest about what it is analyzing. Structural forces do not become less structural because they are also human experiences. Power does not become less powerful because it produces suffering. The analytical and the moral are not separate registers requiring separate treatment. They are dimensions of the same reality, and the writing that can hold them simultaneously — without collapsing one into the other — is the writing that has the best chance of being genuinely useful.

VI. A Note on What Follows

The main essay of this series — Interregnum: Power, Legitimacy, and the Struggle for a New World Order — traces the long genealogy of the current crisis. It begins at Westphalia in 1648 and follows the construction and successive collapses of modern international order through to the present day. It examines the specific structural forces currently eroding the post-1945 system: the redistribution of global power, the return of great-power competition, the crisis of international institutions, the demographic and environmental pressures reshaping the strategic landscape, the technological disruptions rewriting the rules of economic competition and warfare, and the assertive emergence of the Global South as a political force demanding a genuine voice in the design of whatever comes next.

The Afterword — On Power, Suffering, Faith, and the Architecture of Broken Worlds — moves beneath the structural analysis into the philosophical fault lines that run under every systemic transition and that no institutional design has yet resolved. It examines the permanent contest between realpolitik and the legitimacy that power requires to sustain itself. It confronts the crisis of universal ethics in a genuinely multipolar world, and argues for harm reduction — the prevention of identifiable, concrete suffering — as the moral framework most adequate to a world of genuine value pluralism. It takes political Islam seriously as a civilizational force operating outside the conceptual categories of Western social science. And it describes the emerging architecture of hybrid political systems — the configurations combining liberal institutional design, authoritarian governance, market economics, and ethno-religious identity that will constitute the building blocks of the next order.

Together, these three pieces — this Prologue, the main essay, and the Afterword — constitute a single sustained argument. The argument is not optimistic, but it is not despairing. Despair is as much a form of evasion as false comfort. What this series offers instead is the more difficult thing: a clear-eyed account of the structural conditions of the current moment, a rigorous examination of the forces shaping its trajectory, and an insistence on the moral stakes of the analysis that takes both the intelligence and the conscience of the reader seriously.

The old world is dying. The nature of the new world struggling to be born depends, in ways that are not trivial, on how clearly those who will build it are willing to see the one that is ending.

Interregnum: Power, Legitimacy, and the Struggle for a New World Order

The Fracturing of the World Order and the Age That Follows

History rarely announces the end of an era in advance. Most world orders appear stable until, suddenly, they no longer are. Only in retrospect do historians recognize that a familiar structure had already begun to decay long before the moment of visible crisis.

The years before 1914 offer a cautionary example. European statesmen attended international conferences, published optimistic books about the progressive pacification of commerce, and calculated that great-power war had become too costly to contemplate. Fourteen months later the continent was in flames. The system had not failed in any single decisive act; it had quietly hollowed out over decades before the final collapse arrived with a pistol shot in Sarajevo.

Many geopolitical historians today believe we may be living through an analogous period — the early phase of a profound transformation in the international system. Regional conflicts are multiplying. Power balances are shifting. Technological disruption is rewriting the rules of economic competition and warfare. Demographic change and environmental stress are altering the strategic landscape. And the international institutions that were designed to manage these pressures are struggling to retain their legitimacy.

Some scholars frame the current moment as the beginning of a systemic transition, potentially comparable to the turbulent era between 1914 and 1945 — a thirty-year period of upheaval that destroyed the old imperial world order and eventually produced the modern international system. Others argue that the transformation may be even more fundamental: not merely a shift in which powers dominate the existing system, but a structural change in the nature of the system itself.

To evaluate these claims, it is necessary to step back and trace the long historical arc of how global orders form, stabilize, and eventually collapse.

The Birth of the Modern International System

The foundations of the modern state system are usually traced to the Peace of Westphalia in 1648, which ended the catastrophic Thirty Years’ War in Central Europe. That conflict had begun as a religious struggle between Catholic and Protestant powers but evolved into something far more destructive: a continent-wide war of attrition that killed perhaps a third of the German-speaking population and left lasting scars across European civilization.

The Westphalian settlement introduced principles that would shape global politics for more than three centuries. Rulers were recognized as sovereign authorities within defined territories. External powers were formally prohibited from interfering in a state’s internal religious affairs. Diplomacy, balance of power, and formalized negotiation became the mechanisms through which international disputes would be managed.

Critically, the settlement did not create a world of equal, unified nation-states — those would not exist in any modern sense until the nineteenth century. It created instead a framework for managing a world of dynasties, principalities, and city-states by acknowledging that each political unit held a kind of bounded authority over its own domain. The concept was more procedural than ideological: a working agreement that rulers would not pursue unlimited war in each other’s territories.

Over the next century and a half, this framework was tested, refined, and partially reinforced by successive conflicts. The Napoleonic Wars delivered the most severe challenge. Napoleon’s ambition threatened to transform Europe not merely militarily but politically — replacing the established order of dynasties with a continent organized around French hegemony and revolutionary principles. His defeat prompted Europe’s remaining great powers to construct an even more deliberate and self-conscious international system.

The Concert of Europe and Its Limits

The Congress of Vienna in 1815 was one of history’s most consequential diplomatic events. Representatives of Austria, Prussia, Russia, Britain, and eventually France gathered not merely to redraw borders but to design a framework for ongoing great-power management. The resulting Concert of Europe was a genuine innovation: a recurring consultative mechanism through which the major powers would collectively govern the international system, suppressing revolutionary change and managing disputes before they escalated into general war.

For much of the nineteenth century it worked remarkably well. The Crimean War (1853–1856) and the various wars of German and Italian unification were costly, but they remained limited rather than catastrophic conflicts. The concert’s underlying logic — that the great powers had a shared interest in preventing systemic breakdown — proved durable enough to contain the worst impulses of individual states.

But the concert rested on several assumptions that were being eroded throughout the century. It assumed that the major powers would always prioritize system stability over ideological or nationalist ambition. It assumed a rough balance of economic and military power among the leading states. And it assumed that the key actors would remain the same great European dynasties that had designed the system.

All three assumptions were undermined by the industrial revolution and the rise of mass nationalism. By the late nineteenth century, Germany’s explosive industrial growth had disrupted the balance of economic and military power. Mass political movements, driven by nationalist sentiment and class conflict, were making governments more responsive to popular emotion and less able to practice the cold-blooded diplomacy of professional statesmen. Imperial competition was extending the arena of conflict beyond Europe to Africa, Asia, and the Pacific. The congress system was still holding periodic meetings, but the conditions that had made it functional were dissolving beneath it.

The Collapse of the Old Order: 1914–1945

The system built at Vienna did not collapse in a single decisive moment. It unraveled across three turbulent decades, through a sequence of crises that each left the structure weaker and more brittle.

The crisis began with the First World War in 1914. The conflict shattered the balance-of-power architecture that had governed European politics for nearly a century. Four great empires — the Ottoman, Austro-Hungarian, German, and Russian — ceased to exist. Their collapse left behind an unstable array of successor states burdened with unresolved ethnic tensions, contested borders, and political institutions too fragile to manage the pressures they faced.

The peace settlement at Versailles compounded the problem. Rather than constructing a new concert of powers capable of managing the postwar world, the victors imposed punitive terms on Germany, excluded Russia entirely, and created institutions — notably the League of Nations — that lacked the enforcement mechanisms needed to function effectively. President Woodrow Wilson’s vision of collective security was architecturally sound but politically unbuilt; the United States Senate refused to ratify the League covenant, depriving it of the one great power whose participation might have given it genuine force.

Meanwhile the Russian Revolution had introduced a radical new ideological force into world politics. The Soviet state did not merely challenge Western power; it challenged the legitimacy of the capitalist order itself, inspiring revolutionary movements across Europe, Asia, and beyond. International politics now had to accommodate not just competing national interests but competing visions of what kind of political and economic system should govern the world.

The Great Depression delivered the coup de grâce to what remained of the interwar system. The economic catastrophe of the 1930s devastated middle-class living standards across the industrialized world, discredited mainstream political parties, and opened political space for extremist movements offering radical alternatives. In Germany, Italy, and Japan, ultranationalist governments came to power that were explicitly committed to overturning the existing order by force. The democratic states, weakened by depression and haunted by the memory of the last war’s carnage, were slow to respond.

The result was the Second World War — the most destructive conflict in recorded history. Only after its staggering devastation was a new international order finally constructed.

The Architecture of the Post-1945 System

The architects of the postwar world were keenly aware that they were trying to solve a problem that had defeated their predecessors. They knew that the League of Nations had failed. They knew that economic nationalism and competitive devaluation had deepened the Depression. And they knew that unresolved territorial grievances had provided the political fuel for fascism.

Their solution was institutional depth. Rather than a single multilateral forum, they constructed an interlocking network of organizations designed to stabilize different dimensions of international life simultaneously. The United Nations was created to manage diplomatic conflict and provide a forum for collective security. The International Monetary Fund and World Bank were established to prevent the kind of financial instability that had derailed the interwar economy. The General Agreement on Tariffs and Trade created a framework for expanding international commerce. Regional institutions gradually supplemented the global architecture.

The United States, emerging from the war as the dominant global power, provided the system’s ultimate guarantor. American military alliances — most importantly NATO in Europe — anchored Western security. The dollar, pegged to gold and accepted as the global reserve currency, underpinned international trade and finance. American political prestige and economic dynamism lent credibility to the broader project of Western-led international order.

Even the Cold War rivalry between the United States and the Soviet Union operated within a structured geopolitical framework. Both superpowers accepted certain shared rules: nuclear deterrence enforced a rough strategic stability; diplomatic protocols created predictable channels of communication; and both sides recognized, however reluctantly, that direct military confrontation risked mutual annihilation. The ideological competition was fierce, but it was managed within boundaries that neither side was willing to breach.

When the Soviet Union collapsed in 1991, the system appeared to have achieved a kind of final vindication. The United States briefly stood at the center of a unipolar world, and optimistic scholars wrote of the “end of history” — the arrival of a global consensus around liberal democracy and market capitalism. It was a premature judgment. History had merely paused.

The Slow Erosion of the Postwar Order

The erosion of the post-1945 system has not been a single dramatic rupture but a gradual accumulation of stresses, each individually manageable but collectively transformative.

The most fundamental change is the redistribution of global economic and political power. The institutions built after 1945 were designed by and for a world in which a small number of Western states held commanding advantages in industrial output, technological capacity, and military strength. That world no longer exists. China has become the world’s largest economy by purchasing power parity and is rapidly closing the technological gap with the United States. India is on a similar trajectory. Indonesia, Brazil, Nigeria, and other large emerging economies are asserting greater influence in international forums. The combined economic weight of what is sometimes called the Global South now rivals that of the traditional Western powers.

Yet the governance structures of international institutions have not kept pace with this shift. Permanent membership in the UN Security Council still reflects the power distribution of 1945. Voting weights in the International Monetary Fund still favor the original Western contributors. This misalignment between formal institutional power and actual geopolitical weight is generating increasing resentment and delegitimization.

Simultaneously, a broader crisis of institutional trust has been unfolding within states as well as between them. In many democratic societies, confidence in governments, courts, media organizations, and international bodies has fallen sharply over the past three decades. Populist movements across the political spectrum have exploited this distrust, arguing that established institutions serve elite interests rather than popular ones. The political consensus that once sustained the postwar order is fragmenting.

International law and norms have suffered corresponding erosion. The principle of non-interference in states’ internal affairs — already under stress from humanitarian interventions in the 1990s — was severely damaged by the 2003 Iraq invasion, which was launched without Security Council authorization. Russia’s annexation of Crimea in 2014 and full-scale invasion of Ukraine in 2022 represented direct challenges to the territorial integrity norms at the core of the postwar system. The response of Western powers — financial sanctions, military assistance to Ukraine, but no direct intervention — illustrated both the continuing relevance of international norms and the difficulty of enforcing them against a nuclear-armed great power.

The Return of Great Power Competition

At the geopolitical level, the post-1945 era of American primacy appears to be giving way to a more contested multipolar environment. The emerging configuration does not yet have a settled character, but its broad outlines are becoming visible.

The United States retains formidable advantages: the world’s most powerful military, the global reserve currency, an extensive alliance network, and considerable soft power through cultural and technological influence. But American domestic politics have become deeply polarized, generating uncertainty about the reliability of its international commitments. The strategic debate in Washington increasingly centers on whether the United States should remain the guarantor of a rules-based international order or concentrate its resources on narrower national priorities.

China’s rise represents the most significant geopolitical development of the early twenty-first century. Under Xi Jinping, China has pursued a more assertive foreign policy, expanding its military presence in the South China Sea, constructing economic relationships across Asia, Africa, and Latin America through the Belt and Road Initiative, and openly challenging American technological dominance in fields such as artificial intelligence, semiconductors, and 5G communications. China presents itself as an alternative model of state-led development, and its success has given authoritarian governments worldwide both practical support and ideological encouragement.

Russia, though economically far weaker than either the United States or China, remains a disruptive force. Its willingness to use military power directly in Ukraine — accepting enormous costs in blood and treasure — has demonstrated that at least one major power is prepared to challenge the fundamental territorial norms of the postwar order. The war has also had the paradoxical effect of revitalizing NATO and deepening European security cooperation, though whether this consolidation will prove durable remains to be seen.

Regional powers — Turkey, Iran, Saudi Arabia, India, Brazil — are pursuing increasingly independent strategic agendas, declining to align neatly with either the Western bloc or the emerging Chinese sphere. The result is a system of overlapping partnerships, shifting alignments, and strategic ambiguity that defies the simple binaries of the Cold War.

Some analysts describe the emerging order as a new kind of imperial configuration — not territorial empires in the nineteenth-century sense, but large geopolitical blocs organized around dominant powers, each with its own institutional ecosystem, economic dependencies, and cultural influence.

The Middle East as a Fault Line

Few regions illustrate the structural tensions of the transitional moment more vividly than the Middle East. The political geography of the region is itself a product of a previous systemic collapse: the disintegration of the Ottoman Empire after the First World War, when British and French administrators drew borders with instruments calibrated more to imperial convenience than to the ethnic, tribal, and religious geography of the territories they were dividing.

The states that emerged from this process — Iraq, Syria, Lebanon, Jordan, and others — were built on political compromises that were inherently fragile. Their stability typically depended on authoritarian governance: a strong centralized state capable of suppressing the centrifugal pressures of sectarian and tribal division. When those regimes weakened or collapsed, the underlying fractures resurfaced with explosive force.

The 2003 American invasion of Iraq, whatever its strategic intentions, effectively dismantled the state structures that had contained these pressures. The Arab Spring uprisings of 2010–2011 created further instability across the region, producing not democratic transitions but prolonged civil conflicts in Syria, Libya, and Yemen. In each case the pattern was similar: state authority fragmented, external powers intervened to support competing factions, and the conflict became embedded in wider geopolitical rivalries.

The result in several parts of the region is an authority structure that defies the conventional map. Formal governments control some territory; militias, tribal federations, and foreign-backed proxies control the rest. Hezbollah in Lebanon, the Houthis in Yemen, and various Iraqi militia organizations are more powerful than many of the state institutions alongside which they operate. Iran, Turkey, Saudi Arabia, Israel, Russia, and the United States all maintain competing presences within the same theaters.

This fragmentation has led some analysts to argue that parts of the Middle East already resemble what historians call a neo-medieval political system — a configuration in which multiple actors exercise overlapping and competing forms of authority without any single sovereign claiming exclusive control.

The Neo-Medieval Hypothesis

The concept of a “neo-medieval” world was introduced in the 1970s by the British international relations theorist Hedley Bull, who observed that globalization and transnational actors were beginning to complicate the simple Westphalian model of sovereign states as the only significant actors in international politics. The idea has been periodically revisited and expanded since then.

Before the emergence of modern nation-states, medieval Europe was indeed characterized by complex, layered authority. Kings governed kingdoms, but their authority was constrained and shared by feudal lords, the Catholic Church, free cities, merchant guilds, and the Holy Roman Empire. Jurisdiction over any given individual or territory might be claimed simultaneously by multiple overlapping authorities. There was no clear boundary between “domestic” and “international” politics — all politics was local, regional, and universal at once.

The neo-medieval hypothesis suggests that contemporary globalization is producing analogous complexity. Multinational corporations control economic systems that transcend national borders, with supply chains spanning dozens of countries and revenues exceeding the GDP of most states. Digital platforms have created new forms of social and political organization that operate outside national jurisdiction. Private military contractors operate alongside state armed forces in conflict zones. International financial institutions, regional organizations, NGOs, and transnational advocacy networks exercise real political influence.

Global cities — Singapore, Dubai, London, New York, Hong Kong — function as economic hubs whose financial and commercial connections may be as important as the formal sovereignty of the nations containing them. Some scholars suggest that these city-nodes are becoming the primary generators of global economic dynamism, operating in a kind of parallel economy that overlaps with but increasingly transcends traditional state structures.

In this view, the nation-state does not disappear — it remains the primary framework for most people’s political identities and the primary organizational unit of international politics. But it becomes one actor among many in a more complex web of overlapping authorities and jurisdictions. Sovereignty becomes less absolute, more negotiated, and more contested from multiple directions simultaneously.

The neo-medieval model has significant limitations as a predictive framework. Medieval Europe’s political fragmentation was also an era of endemic warfare, plague, and institutional weakness. The analogy can be taken too far. But as a description of the direction in which the international system appears to be evolving — toward complexity, fragmentation, and overlapping authority — it has genuine descriptive power.

Technology and the Transformation of Power

Technological change is accelerating almost all of these structural shifts, compressing timelines and making outcomes more uncertain.

Artificial intelligence represents perhaps the most consequential transformation. AI systems are already reshaping economic production across a wide range of industries, and the pace of development suggests that the disruption is only beginning. If AI automation significantly reduces the demand for human labor in manufacturing, services, and even knowledge work, the traditional relationship between population size and economic output could weaken substantially. Countries that lead in AI development may gain enormous productivity advantages over those that do not, regardless of their workforce size. This possibility is generating intense strategic competition, particularly between the United States and China, both of which have made AI dominance a national priority.

AI is also transforming the character of warfare. Autonomous weapons systems, algorithmic target selection, AI-enabled electronic warfare, and machine-speed cyber operations are forcing military planners to rethink doctrines developed for a slower and more human-centered model of conflict. The proliferation of drone technology — already visible in conflicts in Ukraine, Gaza, and elsewhere — has enabled actors with limited resources to impose significant costs on conventional military forces. Asymmetric warfare, always important, is becoming even more significant.

Cyber conflict has emerged as a continuous dimension of geopolitical competition operating at all levels of intensity simultaneously. States sponsor campaigns of espionage, sabotage, disinformation, and infrastructure attack against rivals without triggering the thresholds that would formally count as war. The boundaries between peacetime competition and armed conflict have become genuinely blurred, raising difficult questions about how international law and the laws of armed conflict apply to operations in cyberspace.

Digital infrastructure has also created a new dimension of sovereignty. Control over data flows, information architectures, and technological standards has become a major geopolitical issue. The “splinternet” — the partial fragmentation of the global internet into distinct national and regional spheres — is already underway. Debates about the governance of artificial intelligence, semiconductor supply chains, and the undersea cable networks that carry most of the world’s digital traffic are increasingly geopolitical in character.

Some analysts argue that informational sovereignty — the ability to control the information environment within a nation’s borders and to project information influence beyond them — may come to rival territorial sovereignty as a defining feature of political power in the twenty-first century.

Climate Change and the New Geopolitics of Survival

No analysis of the current systemic transition can be complete without addressing climate change — a slow-moving but potentially decisive force reshaping the conditions of international politics.

The physical effects of climate change are already visible: rising sea levels, intensifying extreme weather events, shifting agricultural zones, and increasing water scarcity in vulnerable regions. These changes do not create geopolitical instability directly, but they act as force multipliers, amplifying existing tensions over resources, borders, and migration.

Small island states face potential loss of habitable territory, generating legal and political questions about sovereignty and population displacement that international law is not well equipped to answer. Coastal megacities — Jakarta, Miami, Mumbai, Shanghai — face massive adaptation costs or the prospect of partial abandonment. Agricultural disruption in already fragile states could trigger social instability and conflict of the kind that contributed to the Arab Spring, whose origins included the effects of drought and food price spikes on vulnerable populations.

The geopolitics of climate also creates new forms of competition and cooperation. States that can afford large-scale adaptation infrastructure will diverge further from those that cannot. Control over freshwater resources is becoming a source of strategic competition in South Asia, the Middle East, and North Africa. Mass migration driven by climate stress could generate political pressures in receiving countries comparable to the immigration crises of the 2010s — potentially further fueling nationalist politics and institutional strain.

Simultaneously, the response to climate change is reshaping energy geopolitics. For decades, control over oil and gas reserves defined the strategic importance of the Persian Gulf, Russia’s relationship with Europe, and the foundations of several regional power structures. As renewable energy technologies expand and mature, this calculus is shifting. States heavily dependent on fossil fuel revenues — Russia, Saudi Arabia, Iran, several Gulf states — face structural economic challenges as demand patterns change.

New forms of strategic competition are emerging around the raw materials that enable the clean energy transition: lithium, cobalt, nickel, rare earth elements used in batteries, wind turbines, and electric motors. The Democratic Republic of Congo, Chile, Australia, and China currently dominate the supply of key minerals, and their leverage may grow as the energy transition accelerates. Countries that lead in manufacturing clean energy technology — solar panels, batteries, wind turbines, electric vehicles — could gain the kind of geopolitical advantage that oil producers enjoyed in the twentieth century.

The Demographic Shock

Beneath the drama of geopolitical competition and technological disruption, a quieter but equally consequential transformation is unfolding: a global demographic shift that will reshape labor markets, military capacity, migration patterns, and political cultures across the coming decades.

The developed world is aging rapidly. Japan’s median age is now over 49; South Korea, Italy, and Germany are not far behind. China, despite its vast population, is experiencing a demographic slowdown whose effects will become increasingly pronounced over the next two decades — the consequence of decades of the one-child policy and the fertility decline that typically accompanies urbanization and female education. Russia faces a long-term demographic contraction that limits its economic and military potential regardless of its energy revenues.

Aging societies face a characteristic set of pressures: shrinking workforces, rising costs of pensions and healthcare, declining dynamism in innovation and entrepreneurship, and political systems dominated by older voters inclined toward preserving existing entitlements rather than investing in future growth. Managing these pressures while remaining geopolitically competitive is one of the central challenges facing the major established powers.

Meanwhile, many regions of the Global South continue to experience significant population growth. Sub-Saharan Africa’s population is projected to roughly double by 2050. South Asia remains young and growing. These demographic realities create both opportunity and risk: large young populations can be engines of economic growth if they are educated and employed, or sources of instability if they are not.

The interaction between demographic pressure and climate stress in vulnerable regions is particularly significant. In the Sahel, the Horn of Africa, and parts of South and Southeast Asia, population growth is colliding with declining agricultural productivity, increasing water scarcity, and intensifying climate extremes. The result is likely to be sustained pressure for migration — both internal and international — that will test the political and institutional capacity of receiving countries and transit states.

Migration patterns will also shape the demographic futures of receiving countries. States that manage immigration effectively could offset their aging disadvantages; those that cannot manage the political tensions that immigration generates may face both demographic decline and social polarization simultaneously.

The Rise of the Global South

One of the defining features of the current transition is the increasingly assertive international voice of what is loosely called the Global South — the developing and emerging economies of Asia, Africa, Latin America, and the Middle East that together contain the large majority of the world’s population.

During the Cold War, many of these states pursued a formal policy of non-alignment, seeking to avoid subordination to either superpower bloc. After 1991, many were drawn into the frameworks of Western-led globalization — structural adjustment programs, trade liberalization, and democratic conditionality — with mixed results. The 2008 global financial crisis, which originated in the most sophisticated financial markets in the world and then spread its damage globally, severely damaged the credibility of Western economic prescriptions.

Today, Global South states are increasingly unwilling to simply accept the rules and institutions designed by others. They are demanding reform of international financial institutions, more equitable access to technology, and a greater voice in decisions that affect their populations. The BRICS grouping — Brazil, Russia, India, China, and South Africa, subsequently expanded to include several additional members — has become a vehicle for expressing this collective dissatisfaction with the existing order, even if its internal coherence is limited.

Many Global South governments have responded to the geopolitical competition between the United States and China not by aligning with one side but by seeking advantage from both. India is perhaps the clearest example: it maintains close defense relationships with the United States while also engaging with China economically and refusing to condemn Russia’s invasion of Ukraine. This strategic autonomy is not merely pragmatic self-interest; it reflects a genuine belief that the post-1945 rules-based order was designed to preserve Western advantages rather than to promote universal interests.

The challenge for any new global order is whether it can develop institutions and norms that are genuinely inclusive — that reflect the interests and voices of the full range of the world’s states, not merely those that were dominant when the current system was constructed.

The Thirty-Year Crisis Theory

Given the breadth and depth of these structural pressures, some historians and political scientists have advanced what might be called the “thirty-year crisis” theory: the argument that systemic transitions in international politics characteristically unfold over multi-decade periods rather than through sudden ruptures, and that the world may currently be in the early stages of precisely such a transition.

The theory draws primarily on the 1914–1945 experience. That transition did not consist simply of two world wars. It was a cascading sequence of connected crises: the failure of the 1919 peace settlement to create a stable order, the economic catastrophe of the Depression, the ideological radicalization of major states, the collapse of collective security mechanisms, and finally the catastrophic wars themselves. Each stage weakened the system’s capacity to absorb subsequent shocks.

Advocates of the thirty-year crisis theory argue that the current moment shows analogous features. Existing institutions are showing signs of strain. Rising powers are challenging the rules established by their predecessors. Economic disruption is generating political polarization. Regional conflicts are multiplying as states test what the existing order will and will not tolerate. And — critically — the major nuclear powers have not yet found stable mechanisms for managing their geopolitical competition.

The theory should be treated with caution. Historical analogies are never perfect, and the differences between the 1914–1945 period and the present are as important as the similarities. Nuclear weapons create a fundamental constraint on great-power conflict that did not exist in 1914. Global economic interdependence means that the costs of systemic disruption fall on all parties simultaneously. And international institutions, however strained, provide channels for communication and coordination that simply did not exist a century ago.

These factors may be sufficient to prevent a repetition of twentieth-century catastrophe. But they do not eliminate the structural pressures driving the current transition, and there is no guarantee that the mitigating factors will prove adequate to contain them.

The Possibility of a Westphalian Moment in the Middle East

Within this broader structural transformation, some historians speculate that specific regions may eventually experience their own foundational political settlements — analogous, in function if not in form, to what the Peace of Westphalia accomplished in Europe in 1648.

The Middle East presents the most striking case. The political geography of the region was imposed from outside in the aftermath of the Ottoman collapse. It has never produced an internally generated equilibrium among the major powers and communities of the region. For a century, that equilibrium has been maintained either by colonial authority, by American hegemony, or by the brutal efficiency of authoritarian regimes. All three of these stabilizing mechanisms are weakening simultaneously.

A genuine regional settlement would require difficult accommodations: acknowledgment of Iranian regional influence alongside limits on its expansionism; resolution or stable management of the Israeli-Palestinian conflict; new political arrangements in countries such as Syria, Lebanon, and Iraq that acknowledge their internal diversity rather than suppressing it; and negotiated spheres of influence among the competing external powers.

Such a settlement is not imminent. The region is currently moving in the opposite direction, with multiple active conflicts, intensifying sectarian and ethnic tensions, and deepening involvement of external powers. But the historical logic of crisis leading eventually to settlement is real. Europe required the devastation of the Thirty Years’ War before it was willing to accept the mutual accommodations of Westphalia. The Middle East may require its own equivalent period of exhaustion before the conditions for a durable settlement emerge.

The analogy suggests one further uncomfortable implication: Westphalia came only after the conflict had become truly catastrophic. The peace was the product not of wisdom but of exhaustion. If the Middle East follows a similar trajectory, the settlement, when it comes, may be built on ruins.

The Uncertain Future of the Nation-State

Perhaps the deepest question raised by the current transition concerns not which powers will dominate the next order but what kind of political organization will constitute its basic building blocks.

The nation-state has been the dominant form of political organization for roughly two centuries. It combined centralized governmental authority with the mobilizing power of national identity, creating political units capable of extracting resources, projecting power, and commanding popular loyalty on a scale that earlier political forms could not match. The twentieth century saw the nation-state model spread to virtually every part of the globe, replacing empires, kingdoms, and traditional authorities with the apparatus of modern statehood.

But the nation-state model is under pressure from multiple directions simultaneously. From above, globalization has transferred significant authority to international institutions, financial markets, and transnational corporations. From below, subnational identities — regional, ethnic, religious, cultural — are asserting themselves against the homogenizing project of the national state. From the side, digital networks and platforms are creating new forms of community and political mobilization that operate outside the boundaries of state authority.

The result is a growing tension between the formal architecture of international politics — which still treats states as the primary actors — and the practical reality of a world in which authority is increasingly fragmented, contested, and distributed across multiple levels and types of actors.

Future political structures may need to accommodate multiple overlapping layers of governance: local and regional authorities, national states, regional blocs, global institutions, and new digital governance frameworks, all exercising different kinds of authority over the same populations. Whether such multi-layered systems can be democratic, legitimate, and effective simultaneously is one of the central political challenges of the coming decades.

A World Between Orders

Periods of systemic transition are often profoundly disorienting to those living through them. The old rules appear to be losing their force, but new rules have not yet been established. Actors are uncertain about what commitments will be honored, what institutions can be trusted, and what behavior will be rewarded or punished. This uncertainty itself becomes a source of instability, as states hedge against multiple contingencies, make commitments they are unwilling to enforce, and test limits they are not certain exist.

The early twentieth century was exactly such a period. Between 1914 and 1945 the world experienced revolution, economic collapse, ideological radicalization, and catastrophic war before a new global order emerged from the rubble. The architects of that order — the framers of the UN Charter, the Bretton Woods institutions, and the postwar alliance system — were extraordinarily ambitious and, on balance, remarkably successful. They built institutions that proved durable enough to manage the Cold War, enable the longest period of great-power peace in modern history, and facilitate the greatest expansion of global prosperity ever recorded.

Whether the present era will produce comparable institutional creativity remains an open question. There are reasons for cautious optimism: the architects of the next order will have the enormous advantage of the last one’s example, both its successes and its failures. Nuclear deterrence, global economic interdependence, and the existence of international institutions — however strained — provide guardrails that did not exist in 1914. Climate change, for all the political difficulties it creates, also provides a powerful argument for international cooperation, since no state can solve it unilaterally.

But there are also reasons for serious concern. The world is more complex than it was in 1945, making institutional design harder. The United States, which provided the indispensable political and economic foundation of the postwar order, is internally divided about whether it wishes to continue in that role. China and other rising powers are unlikely to accept an order they had no hand in designing. Technological change is outpacing the capacity of existing institutions to govern it. And the window for managed transition may be narrower than it appears, given the pace at which climate change, demographic shifts, and geopolitical competition are simultaneously reshaping the environment.

The structural pressures reshaping the global system are undeniable. Power is shifting. Technology is transforming economies and warfare. Demographic and environmental changes are altering the strategic landscape. Institutions built for a previous era are struggling to adapt. And the political coalitions that sustained the postwar order in the major democracies are under severe internal pressure.

The world may therefore be entering what historians sometimes call an age between orders — a period when the structures of the past are dissolving and the architecture of the future has not yet been built. Such periods are characterized by danger and possibility in equal measure. The old certainties provide diminishing guidance. The new ones have not yet been established.

In such moments, the most important historical question is not who wins individual conflicts, or which great power emerges dominant in the near term. It is what kind of international system eventually emerges from the turbulence — whether it will be more just, more stable, and more capable of managing the challenges of the twenty-first century than the one it replaces.

Because it is in these transitional periods, when old structures are dissolving and new ones remain unformed, that the most consequential political choices are made. The architects of the next order — whoever and wherever they are — are working now, in conditions of uncertainty and pressure that would have been familiar to their predecessors in 1945. Whether they will rise to the occasion as those predecessors did remains, as yet, an open question.

Afterword

On Power, Suffering, Faith, and the Architecture of Broken Worlds

The question is never simply who wins. The question is always what kind of world the winning produces.

The preceding essay traces the anatomy of world orders: how they are born from catastrophe, how they stabilize and calcify, and how they eventually succumb to the pressures of powers and forces they were not designed to contain. That architecture of analysis is necessary but insufficient. It describes the machinery of history without confronting the experience of those ground beneath it. It maps the transitions without asking what we owe each other during the passage.

This afterword attempts something different. It does not extend the historical survey. It moves beneath it — into the philosophical fault lines that run under every systemic transition, the moral tensions that no institutional design has yet resolved, and the forces that conventional geopolitical analysis tends to treat as irrational, exotic, or simply inconvenient. It is concerned with what is left out when we speak of “orders” and “systems” rather than of people, communities, faiths, and the long experience of organized suffering.

Four intersecting themes will be pursued here. First, the ancient contest between realpolitik and legitimacy — between power as it actually operates and power as it must justify itself to survive. Second, the deepening crisis of universal ethics in a genuinely multipolar world: whether justice can mean anything beyond the preferences of the currently dominant, and what the answer implies for those who must live inside the uncertainty. Third, the phenomenon of Islam as a transnational political force — not merely a religion but a civilizational grammar capable of generating revolutionary political programs, mass mobilizations, and structural disruptions that cannot be predicted from within the frameworks of Western social science. And fourth, the emergence of new hybrid systems of power — configurations that combine elements of Western liberal thought, technological architecture, ethno-religious mobilization, and market dynamics in ways that conventional political theory has not adequately described. These themes converge on a single underlying question: in a world of fragmented authority, contested values, and recurring catastrophe, what does it mean to act responsibly?

— ✦ —

I. The Permanent War Between Power and Its Justification

Realpolitik, in its classical formulation, begins with an observation that feels like honesty: states act in their interests. They pursue power, security, and advantage. They dress these pursuits in the language of morality, law, and justice — but that language is primarily instrumental, a coating applied to decisions already made on other grounds. The dress may be necessary; naked power is hard to sustain politically. But the dress is not the body.

This position has an enduring appeal precisely because it is so frequently confirmed by evidence. The United Nations Security Council was designed to enforce international law but has functioned primarily as an arena where great powers protect their interests behind a veto. Humanitarian interventions in the 1990s — Kosovo, Somalia, Rwanda, Bosnia — were shaped as much by the strategic calculations of intervening powers as by the scale of suffering they claimed to address. Rwanda, where the strategic calculation argued for inaction, was left to burn. Kosovo, where NATO credibility was at stake, received military intervention. The gap between the moral language and the actual decision rule was not incidental; it was structural.

And yet realpolitik, pursued without remainder, consumes itself. The legitimacy of political authority — within states and between them — is not merely decorative. It is functional. States that cannot justify their power to their own populations, or to the international community, face resistance, defection, and eventual fragility that purely material analysis consistently underestimates. The Soviet Union was not materially defeated; it was delegitimized. The American project in Iraq was not militarily overmatched in its initial phase; it failed because it could not construct a political framework that local populations were willing to accept. Legitimacy is not the opposite of power. It is the form of power that self-reproduces.

The tension between these two positions has never been — and perhaps cannot be — resolved. What shifts across historical periods is the balance point: how much legitimating justification power requires to sustain itself, and how much naked force it can deploy before the justification erodes beyond recovery. In periods of systemic transition, that balance point becomes unstable. Old legitimating frameworks lose their hold before new ones are established. The interregnum is characterized precisely by the fact that power must operate without adequate justification — which is one reason why transitional periods are so consistently violent.

The current moment is such an interregnum. The post-1945 legitimating framework — the UN Charter, the Universal Declaration of Human Rights, the norms of sovereignty and non-interference — retains formal authority but is being violated with increasing frequency and decreasing consequence. China’s detention of Uyghur populations, Russia’s invasion of Ukraine, the international community’s failure to prevent mass atrocities from Myanmar to Sudan to Gaza — each of these episodes both reflects and deepens the erosion of the framework’s actual authority. What has not yet emerged is a new framework capable of commanding comparable consent across the full range of the world’s states and populations.

Into this legitimacy vacuum, two temptations rush simultaneously. The first is the pure realist temptation: to abandon the pretense of universal norms and acknowledge openly that international politics is simply competition among organized powers, each pursuing its interests, with weaker parties bearing the consequences. The second is the legalist temptation: to cling more tightly to existing norms, treating every deviation as a crisis to be reversed rather than a signal of the framework’s inadequacy. Both temptations are forms of intellectual comfort. The realist temptation relieves the burden of moral responsibility. The legalist temptation relieves the burden of confronting the possibility that the existing framework is genuinely broken rather than merely stressed.

A more honest position acknowledges the inadequacy of both escapes. Power without legitimacy is predatory and ultimately self-defeating. But legitimacy frameworks that claim universality while encoding the preferences of a particular historical moment and a particular set of powers are not genuinely universal. The task — which is easier to describe than to accomplish — is to construct legitimating frameworks that are both effective and genuinely inclusive: that reflect not merely the values of the currently dominant but the interests and moral intuitions of the full range of human communities.

This is not a utopian aspiration. It is a practical precondition for any sustainable international order. The postwar order worked as well as it did partly because its architects were willing to make it genuinely multilateral — imperfectly, unevenly, but meaningfully. The question of whether the architects of the next order will possess comparable wisdom and comparable political will is one of the most consequential open questions of the coming decades.

II. The Collapse of the Universal and the Ethics of Harm Reduction

If the realpolitik-legitimacy tension is about how power justifies itself, the deeper philosophical question is whether there is anything independent of power by which justification can be measured. This is the terrain of ethical relativism versus universal justice — and it is terrain on which the current systemic transition is generating acute disorientation.

The post-1945 international order was built on a claim that was itself philosophically ambitious: that certain rights belong to all human beings by virtue of their humanity, regardless of their political membership, cultural context, or the preferences of their rulers. The Universal Declaration of Human Rights (1948), the subsequent covenants on civil and political rights and on economic and social rights, and the development of international humanitarian law all expressed this aspiration. They declared that there were limits on what states could do to their own populations and to each other — limits grounded not in the preferences of the powerful but in the nature of the human person.

This framework has always been contested, and not merely by authoritarian states seeking to evade accountability. The contestation runs deeper. Philosophical traditions outside the Western liberal mainstream have challenged whether the specific content of “universal” rights actually reflects universal human values or the particular historical experience and cultural assumptions of Western European modernity. The emphasis on individual rights over collective duties, on political and civil freedoms over economic and social rights, on secular governance over religiously grounded authority — each of these choices reflects a particular philosophical tradition, not a view from nowhere.

The emergence of genuine multipolarity is giving these philosophical challenges greater political force. China explicitly rejects the primacy of individual rights over social stability and collective welfare, advancing what it describes as a “community of shared future for mankind” — a language of universalism that leads to very different policy conclusions than the liberal version. Islamic political thought, in various forms, insists that legitimate authority must be grounded in divine law rather than secular social contract. Hindu nationalism in India is constructing a majoritarian conception of political community that assigns different statuses to different religious communities. These are not merely cynical claims made to deflect criticism; they are expressions of deeply held philosophical and theological commitments that have long intellectual traditions and genuine popular support.

The temptation, facing this diversity, is to retreat to a pure relativism: to say that there are no universal standards, only culturally specific ones, and that the attempt to apply universal norms across cultures is itself a form of imperialism. This position has a certain intellectual modesty to recommend it. But it leads to conclusions that are morally intolerable: that systematic torture is not wrong if a sufficiently large community endorses it; that the subjugation of women is beyond criticism if embedded in cultural practice; that genocide is merely a local matter.

The alternative — to insist on the full program of liberal universal rights in the face of multipolar challenge — risks the opposite error: mistaking particular cultural content for universal form, and using the language of human rights to suppress legitimate diversity while advancing Western geopolitical interests.

Between these two errors lies a narrower path that is harder to walk but more honest. There may be a genuine core of trans-cultural moral commitments — to the prohibition of torture, to the protection of children from exploitation, to the principle that human beings should not be systematically destroyed on the basis of their identity — that commands something close to universal consent when stripped of their culturally specific wrappings. And there may be a much larger domain of institutional and social arrangements where genuine diversity is legitimate and where the attempt to enforce a single model produces more harm than it prevents.

Harm reduction, in this context, becomes not a counsel of despair but a practical moral framework. In a world of irresolvable value pluralism and multiple competing centers of power, the relevant question is not “what would a perfectly just world look like?” but “what are the specific, concrete harms we can reduce from where we actually stand?” This shift of focus — from the architecture of ideal justice to the prevention of identifiable harm — does not require abandoning universal commitments. It requires translating them into operational priorities that can command broader cross-cultural consensus than the full liberal package, and that can therefore be enforced rather than merely proclaimed.

The waves of suffering that have attended every major systemic transition in recorded history should give this harm-reduction calculus its appropriate urgency. The transition from the nineteenth-century order to the post-1945 system cost, conservatively, one hundred million lives — in two world wars, in the Armenian Genocide, in the Stalinist terror, in the Holocaust, in the famines produced by deliberate policy and economic collapse. These deaths were not incidental side effects of an otherwise orderly transition. They were structurally connected to the breakdown of legitimating frameworks, the intensification of ideological and ethnic mobilization, and the failure of institutions designed to manage the conflicts of a previous era. If the current transition generates comparable disorder — without the mitigating factors of nuclear deterrence and economic interdependence proving adequate — the potential scale of suffering is difficult to comprehend.

This is not an argument for paralysis, or for the preservation of existing arrangements regardless of their injustice. Unjust orders produce suffering too, and the attempt to preserve them indefinitely typically generates the convulsive reactions it was designed to prevent. It is an argument for treating the prevention of mass suffering as the first-order moral priority in a period of systemic transition — and for being deeply skeptical of any political program, however theoretically beautiful, that requires passing through a valley of mass death to reach its promised destination.

III. Islam as Architecture: The Black Swan That Was Always There

No force in contemporary world politics is more systematically misunderstood by conventional geopolitical analysis than political Islam. Western international relations theory, rooted in the Westphalian tradition of secular sovereign states, tends to treat religious mobilization as a residual phenomenon — something that will eventually be displaced by modernization, or that serves as a vehicle for interests that are “really” ethnic, economic, or political. Neither assumption has aged well.

Islam is not primarily a disruptive force in contemporary politics because of poverty, or humiliation, or the operations of specific radical organizations. It is disruptive because it offers something that secular modernity structurally cannot: a comprehensive account of how human social and political life should be organized that is grounded in transcendent authority rather than in the shifting preferences of democratic majorities or the calculations of market actors. For populations that have experienced modernity primarily as dispossession, foreign domination, and cultural erasure, this offer has a power that cannot be analyzed away.

The genealogy of political Islam’s disruptive potential in the late twentieth century begins not with a single organization but with a series of events that together demonstrated the system’s vulnerability to a force operating outside its conceptual categories. The Iranian Revolution of 1979 was the first and most consequential shock. A sophisticated, oil-rich state with a powerful military, integrated into the Western economic system and allied with the United States, was overthrown not by a Marxist vanguard or a military coup but by a popular religious mobilization that produced an entirely new form of political organization — the Islamic Republic, a system of governance grounded in Shia jurisprudential authority rather than any existing template of modern statehood.

The revolution’s significance was not merely geopolitical. It was conceptual. It demonstrated that modernization theory — the assumption that economic development and social change would naturally produce secular liberal institutions — was wrong, or at least incomplete. A society that had been rapidly modernizing for two decades produced not a more stable liberal democracy but a revolutionary rejection of the entire Western-imposed developmental framework. Modernity had deepened the social disruption without delivering the promised political stability or cultural coherence.

The Soviet invasion of Afghanistan, beginning the same year, generated a second, differently structured but equally consequential phenomenon: the mobilization of transnational Islamic fighters — the mujahideen, many of them funded and armed by the United States, Saudi Arabia, and Pakistan — against a secular superpower. The defeat of the Soviet Union in Afghanistan was, among other things, a demonstration that transnational Islamic mobilization could generate military capabilities capable of defeating a great power’s conventional forces in irregular warfare. The lesson was absorbed widely.

The September 2001 attacks represented a further evolution: the deployment of transnational religious networks to conduct spectacular asymmetric violence against the world’s dominant power on its own territory. The attacks did not, in any conventional military sense, damage American power. What they did was force the United States to commit enormous resources to a “Global War on Terror” that ultimately weakened American strategic position in precisely the regions where its credibility mattered most. The provocation worked — not because al-Qaeda was strong, but because it correctly predicted how the United States would respond.

The return of the Taliban to power in Afghanistan in 2021 — after twenty years of American military presence, hundreds of billions of dollars of investment, and the construction of formal democratic institutions — represents perhaps the clearest demonstration yet of the limits of modernization theory and the durability of Islamic political frameworks rooted in local cultural authority. The Taliban did not win because they offered a superior development model. They won because they represented a form of social organization — tribal, Islamic, and locally legitimate — that proved more resilient than the externally imposed structures built atop it.

But to focus only on al-Qaeda, ISIS, the Taliban, and Iran is to mistake the dramatic examples for the structural phenomenon. Between these high-profile actors lies an enormously diverse ecosystem of Islamic political movements, parties, networks, and communities operating across every continent. Hamas in Gaza. Hezbollah in Lebanon. The Muslim Brotherhood and its various national affiliates across the Arab world. Hizb ut-Tahrir in Central Asia and beyond. The growing networks of political Islam in sub-Saharan Africa, from Nigeria’s Boko Haram to the Sahel’s Jama’at Nusrat al-Islam wal-Muslimin. The Islamic political parties operating within formal democratic systems in Turkey, Tunisia, Morocco, Indonesia, and Malaysia. The transnational networks of Islamic finance, education, and charity that create soft-power connections across national borders.

These actors do not share a unified program. The differences between Shia political theology and Sunni variants, between Salafi and Sufi approaches to politics and society, between those who accept democratic participation and those who reject it, between the globally oriented networks and the locally rooted movements — these are real and consequential. Political Islam is not a monolith. It is a civilizational grammar, and like all grammars it generates an enormous variety of sentences.

What the grammar shares — what makes Islam a genuinely transnational political force rather than simply a collection of local religious communities — is a set of core commitments: to the unity of the divine and the derivative authority of divine law; to the community of believers (the ummah) as a solidarity unit that transcends national borders; to the illegitimacy of purely secular authority in matters of social and moral governance; and to the belief that Islam provides a comprehensive way of life, not merely a private spiritual practice. These commitments generate political implications that cut across the conventional categories of Western political science.

The black swan quality of political Islam — its capacity to generate large-scale, rapid, and structurally unexpected disruptions — derives from the interaction between these shared commitments and specific triggering conditions. The conditions are not exotic. Perceived humiliation of Muslim populations, corruption and failure of secular governments, the availability of communication networks for transnational mobilization, and the existence of charismatic religious leadership capable of translating spiritual grievance into political program — these are all present, in varying degrees, across a wide range of countries and regions.

What makes the disruptions genuinely unpredictable is that Islamic political mobilization does not follow the linear logic of conventional political science. It does not mobilize primarily around economic interests. It is not straightforwardly contained by repression, which often amplifies rather than reduces radicalization. It does not respect the boundaries of the secular nation-state as the natural unit of political organization. And it can achieve rapid scale through existing social and institutional networks — mosques, madrasas, Islamic financial systems, pilgrimage networks — that exist independently of any specific political organization.

Looking forward, the structural conditions for continued Islamic political disruption are deeply embedded in the demographic and political landscape of the coming decades. The populations of Muslim-majority countries are overwhelmingly young. Many of their governments are simultaneously corrupt, repressive, and unable to deliver economic development. Climate stress and demographic pressure are intensifying competition for resources in the Sahel, the Middle East, South Asia, and Central Asia — all regions with large Muslim populations. The combination of youthful populations, failing states, environmental stress, and the powerful transnational identity offered by Islam is precisely the mixture that has historically generated major political upheavals.

None of this implies that political Islam will “win” in any simple sense — that the world will be reorganized around an Islamic political framework. The internal divisions within Islam are too deep, the resistance of other civilizational blocs too strong, and the practical governance challenges too formidable for any such outcome. What it implies is that Islam will be one of the primary forces shaping the contours of the next international order — not as an external disruption to an otherwise comprehensible system, but as a constitutive element of the system’s political architecture, whose preferences and dynamics cannot be analyzed away.

IV. The Architecture of Hybrid Power: Where Systems Learn to Feed on Themselves

The international system that eventually emerges from the current transition will not be organized according to any single political theory. It will not be the triumph of liberal democracy, nor the victory of authoritarian capitalism, nor the installation of any form of theocratic governance. It will be something harder to name and harder to analyze: a set of overlapping hybrid systems, each combining elements of different ideological traditions, technological capabilities, and identity frameworks in ways that are specific to their histories and strategic environments, and that interact with each other in dynamics that resist the frameworks of either classical realism or liberal institutionalism.

The emergence of these hybrid systems is already visible. China’s political economy represents a combination that defies the conventional dichotomy between state and market: a Leninist party structure combined with market mechanisms, managed globalization, and a national identity narrative that draws simultaneously on Confucian tradition, revolutionary Marxism, and techno-nationalist aspiration. It is neither the liberal end-state of modernization theory nor a simple return to traditional autocracy. It is a genuinely novel synthesis — and one that has proven capable of generating sustained economic growth and political stability in conditions where Western models repeatedly failed.

Turkey under Erdogan represents a different hybrid: the combination of democratic electoral mechanics with Islamist cultural politics, Ottoman historical nostalgia, and a strategic nationalism that refuses alignment with either the Western or the Chinese bloc. India under Modi is constructing yet another configuration: a Hindu nationalist cultural framework layered over a democratic institutional structure, pursuing non-alignment in great-power competition while deepening market integration with the global economy. Russia’s current system — a kind of Orthodox nationalist Bonapartism, combining security-state authoritarianism with oligarchic capitalism and civilizational messianism — is another variant.

What these hybrids share is not their content but their structural logic: they all represent the adaptation of pre-existing cultural and ideological resources to the demands of modern state power and global economic competition. They are not aberrations from a norm. They are the norm. The idea that modernization would produce convergence toward a single institutional template — the liberal democratic market state — was always more ideological than empirical. The actual trajectory of political development has always been toward diversity, as different societies draw on different cultural resources to construct the institutional forms through which they manage their specific historical challenges.

The technological dimension is accelerating this differentiation rather than homogenizing it. Digital communication technologies were initially understood as vectors of liberal political change — the Arab Spring’s “Facebook revolutions” seemed to confirm this narrative. What became apparent subsequently was that the same technologies could be deployed with equal effectiveness for authoritarian control, surveillance capitalism, ethno-nationalist mobilization, and transnational religious organization. The technology is not ideologically neutral, but its ideological biases are more subtle and more variable than early enthusiasts recognized.

Artificial intelligence amplifies the stakes of this technological differentiation. States that develop leading AI capabilities will gain advantages in economic productivity, military effectiveness, and the capacity to surveil and control populations that could lock in political advantage for decades. But the specific character of those advantages — whether they will be deployed for liberal or authoritarian ends, whether they will reinforce existing state structures or create new forms of authority — will depend on the political and cultural contexts within which they develop. AI in China will be shaped by Chinese political priorities. AI in Iran will be shaped by Iranian ones. AI in Silicon Valley will reflect the cultural assumptions and economic incentives of American technology capitalism.

The feedback dynamics between technology, political structure, economic system, and identity framework are what make hybrid systems so difficult to analyze using conventional theoretical tools. Classical realism treats states as unitary actors pursuing fixed interests. Liberalism treats institutional design as the primary variable determining political outcomes. Neither framework captures the recursive, self-reinforcing dynamics through which hybrid systems evolve.

A more useful frame may be drawn from complex systems theory: the idea that the relevant unit of analysis is not the individual actor or institution but the system’s overall architecture — the pattern of feedback loops, equilibria, and instabilities that determines how the system responds to perturbations. In this frame, political Islam is not merely an external force acting on a static system; it is a component of the system that changes the system’s dynamics through its interactions with technology, demography, failed states, and great-power competition. China’s rise is not merely a shift in the distribution of power within an existing system; it is a structural change in the system’s feedback dynamics, altering the incentives and constraints of every other actor.

Game theory offers an additional analytical lens, though one with important limitations. The interactions between major actors in the current transition have the character of complex games with many players, incomplete information, evolving payoff structures, and no neutral authority capable of enforcing agreements. Classical deterrence theory, developed for the two-player nuclear standoff of the Cold War, is inadequate for this complexity. Modern game-theoretic approaches to multi-player, multi-issue bargaining are more useful — but they still struggle to incorporate actors whose motivations include non-material goods: divine mandate, civilizational honor, martyrdom, historical vindication. Religious and identity-based actors play a fundamentally different game from interest-maximizing states, and the interaction between these different game logics generates outcomes that neither framework can predict.

This is where the power of religion as a systemic variable becomes analytically indispensable. Religion does not merely supply a set of preferences that can be plugged into a utility function. It supplies a framework for evaluating what counts as winning, what constitutes an acceptable cost, and what kinds of commitments are non-negotiable. An actor who believes that God commands a particular course of action has a fundamentally different cost-benefit structure than one calculating material interest. This is not irrationality; it is a different rationality, one calibrated to a different conception of what matters.

The inclusion of religiously grounded actors — not only Islamic but also Evangelical Christian movements in American politics, Hindu nationalism in India, Jewish religious nationalism in Israel, Buddhist nationalism in Myanmar and Sri Lanka — in any adequate model of contemporary international politics is not optional. These actors are shaping outcomes in ways that pure structural and interest-based analyses consistently fail to predict. Their relationship to the hybrid systems described above is not incidental: ethno-religious mobilization is one of the primary resources through which hybrid political systems generate popular legitimacy and sustain political coalitions. Modi’s Hindu nationalism, Erdogan’s political Islam, Putin’s Orthodox Christian civilizationism — each of these is a case study in the strategic deployment of religious identity as a technology of political power.

The feedback loop between market dynamics and political-religious mobilization deserves particular attention. Islamic finance — the construction of financial instruments and institutions compatible with Quranic prohibitions on usury — has grown into a multi-trillion-dollar sector operating across dozens of countries. It is simultaneously a commercial enterprise, a political statement, an identity practice, and a transnational infrastructure. It creates economic incentives for the spread of Islamic governance norms, generates institutional linkages between Islamic political movements across national borders, and provides a degree of economic autonomy from the Western-dominated financial system. It is, in microcosm, an example of how religious principle, market mechanism, and political strategy can evolve into a self-reinforcing system architecture.

Analogous dynamics are visible in the relationship between Chinese state capitalism and Belt and Road infrastructure development: the creation of economic dependencies that simultaneously serve commercial interests, generate political leverage, and construct an alternative institutional ecosystem to the Western-dominated one. Or in the relationship between American technology platforms and the spread of specific forms of political culture: the platforms’ economic incentives (engagement maximization) interact with users’ psychological tendencies (outrage, tribal solidarity) to produce political polarization that undermines the institutional consensus on which the platforms’ own operating environment depends.

These are all examples of systems that produce consequences their designers did not intend, that evolve beyond the control of any single actor, and that interact with each other in ways that generate emergent outcomes not visible from within any single analytical framework. They are the signature of a genuinely complex transitional moment.

V. Synthesis: Navigating the Age Between Orders

The themes pursued in this afterword converge on a set of insights that are not easily systematized but are, I believe, necessary for any honest engagement with the world that is coming into being.

The first is that the contest between realpolitik and legitimacy is not a problem to be solved but a tension to be managed. Power requires justification to sustain itself over time, but justification frameworks always reflect the preferences of those who design them. The most durable international orders have been those that managed to embed genuine accommodations of diverse interests within their legitimating frameworks — not perfectly, but sufficiently to prevent the framework from being experienced as pure imposition by a critical mass of its subjects. The design challenge for the next order is to create legitimating frameworks capacious enough to accommodate genuine value diversity while maintaining sufficient common ground to prevent the complete fragmentation of international governance.

The second is that ethical relativism and universal justice are both inadequate as responses to moral pluralism. The minimum universal floor — the protection of human beings from systematic destruction, torture, and subjugation — is achievable as a practical political project without requiring agreement on the full program of liberal rights. The maximum program — the imposition of a single institutional template across human cultures — is neither achievable nor desirable. Between these poles lies a large space of legitimate political experimentation that ought to be protected rather than policed.

The third is that suffering is not a rounding error in the analysis of systemic transitions. It is the central data point. The question of how to minimize the human cost of the transition currently underway — in lives, in displacement, in the particular horror of deliberate atrocity — is not secondary to the structural analysis. It is its moral purpose. An analysis that maps the architecture of systems without accounting for the waves of destruction they generate when they fail is not sophisticated. It is evasive.

The fourth is that Islam is not a problem to be managed at the margins of a predominantly Western-designed global order. It is a civilizational presence of the first order, carrying political, philosophical, and organizational resources that will shape the architecture of the next international system in ways that have not yet been fully reckoned with. The failures of secular nationalism and externally imposed modernization across much of the Muslim world have not eliminated the demand for legitimate governance; they have redirected it toward Islamic political frameworks that have deep historical roots and genuine popular support. Any international order that does not create space for these frameworks — that treats them as deviations from a norm rather than as legitimate expressions of political and cultural preference — will face the same legitimacy deficits that have undermined the current order.

The fifth is that the emergence of hybrid political-economic-cultural systems is the most important structural feature of the coming order. These systems are not transitional forms on the way to some final convergence. They are the mature products of different histories encountering shared challenges. They will compete, interact, and borrow from each other in ways that produce continuous evolution. The task of international governance is not to select one of them as the universal template but to create frameworks within which their competition remains non-catastrophic — in which the feedback loops between market dynamics, technological capability, identity mobilization, and great-power competition do not generate the kind of runaway dynamics that produced the catastrophes of 1914–1945.

The sixth — and perhaps the most difficult — is that religion is not an archaism to be overcome but a permanent feature of the human political landscape. The secular assumption that modernization would progressively displace religious motivation from politics has proven, empirically, to be wrong. What modernization has done is change the form that religious political mobilization takes — making it more transnational, more technologically mediated, more capable of operating within formal democratic institutions — without reducing its underlying force. Any political theory, any institutional design, any analysis of the next international order that does not account for the power of religious motivation is missing one of the primary drivers of the transition it claims to describe.

History, viewed at sufficient distance, has a terrible beauty to it. The great transitions — from antiquity to the medieval, from the medieval to the modern, from the imperial world to the post-1945 order — appear from that distance as necessary passages, productive destructions, the clearing of ground for new forms of human organization. The suffering they contained is acknowledged, catalogued, and eventually absorbed into the narrative of progress.

But the transitions are not experienced at distance. They are experienced close-up, by people who did not choose the historical moment into which they were born, who have no guarantee that the order on the other side will be better than the one being destroyed, and who must navigate the passage without maps adequate to the terrain. The ethical question for those of us who analyze these transitions — who have the extraordinary privilege of doing so from safety, with adequate information, and with time to think — is whether we are willing to take seriously the full weight of what that experience contains.

The world is not short of analytical frameworks. It is short of the political will to apply what those frameworks reveal about the conditions under which catastrophe becomes less likely. It is short of institutions capable of managing complexity rather than just reflecting the preferences of the powerful. It is short of leaders willing to invest in the legitimacy of the international system rather than harvesting short-term advantage from its erosion. And it is short of a broadly shared moral language capable of holding together a genuinely diverse world without either imposing false uniformity or dissolving into pure relativism.

These deficits are not inevitable features of the human condition. They are the products of specific choices made by specific actors operating within specific institutional constraints. They can, in principle, be addressed. The question — as it has always been, at every hinge point in human history — is whether enough people with enough power and enough wisdom will choose to address them before the cost of not doing so becomes catastrophic.

History does not guarantee good outcomes. It offers only the record of what has been possible, and the witness of those who paid the price when possibility was squandered.
