Iran, Ukraine and Europe: Are We Watching the End of the Post-Cold War Consensus?

SUNDAY ESSAYS

6/7/2026

The most important stories dominating global headlines this week appear, at first glance, to have little in common. Iran launches missiles and drones toward the Strait of Hormuz following U.S. military action. Ukraine expands its drone campaign deep into Russian territory while hopes for direct negotiations remain distant. European leaders gather to commemorate D-Day as debates intensify over migration, security and the continent’s future direction. A neo-Nazi candidate reaches a mayoral runoff in Germany. The Pope uses a visit to Spain to warn against polarisation and defend support for migrants. Meanwhile, political tensions in Senegal highlight the growing strains affecting democracies far beyond Europe and North America.

Viewed separately, these stories belong to different regions and different political contexts. Viewed together, they point toward something much larger. They suggest that the assumptions which shaped much of international politics after the Cold War are becoming increasingly difficult to sustain.

For more than three decades, the dominant belief across much of the world was that economic integration, expanding trade, international institutions and growing interdependence would gradually reduce the likelihood of major conflict. The post-Cold War era was not free from war or instability, but there remained a broad expectation that globalisation and cooperation would continue pushing the international system toward greater predictability. Security challenges existed, yet they were often viewed as exceptions rather than defining features of the age. The collapse of the Soviet Union appeared to validate the idea that political liberalisation, economic integration and international cooperation represented the natural direction of history.

That confidence is now being tested from multiple directions simultaneously.

The situation involving Iran and the Strait of Hormuz represents one of the clearest examples. The waterway remains one of the most strategically important corridors in the global economy, carrying a significant share of the world’s energy exports. For years, markets operated under the assumption that while tensions would periodically rise, the basic functioning of the system would remain intact. Recent developments suggest that the assumption can no longer be taken for granted. The prospect of military escalation involving Iran immediately raises concerns about shipping, energy markets, inflation and global economic stability. A regional confrontation rapidly becomes a global issue because the world remains deeply dependent on a handful of critical routes and systems.

The significance of this week’s developments is not simply that tensions increased. It is that they remind governments and markets alike how vulnerable modern globalisation remains to geopolitical shocks. The infrastructure underpinning the global economy is remarkably efficient, but efficiency often comes at the cost of resilience. When disruption occurs at a strategic chokepoint, consequences extend far beyond the immediate region. Policymakers spent much of the post-Cold War period discussing globalisation primarily in terms of opportunity. Increasingly, they are discussing it in terms of vulnerability.

This change in thinking is visible across governments, businesses and financial markets. Supply chains are being reassessed. Strategic industries are receiving government support. Critical infrastructure is increasingly viewed through a national security lens. The assumption that economic efficiency should always be prioritised is giving way to a more complicated conversation about resilience, redundancy and strategic autonomy. The world is not abandoning globalisation, but it is becoming more cautious about dependence.

At the same time, Ukraine continues to challenge another foundational assumption of the post-Cold War era: that large-scale interstate war had become unlikely in Europe. The conflict has evolved far beyond the expectations many observers held during its early stages. What was once viewed as a regional security crisis has become a defining event for European politics, NATO strategy and broader geopolitical competition.

This week’s reports of large-scale Ukrainian drone operations inside Russia are particularly significant because they illustrate how warfare itself is changing. Modern conflicts are increasingly shaped by technology, innovation and adaptation. Drones, cyber capabilities and long-range precision systems allow actors to project power in ways that would have been difficult to imagine only a generation ago. Geography still matters, but technology increasingly changes how geography is experienced.

More importantly, the conflict has forced Europe to confront uncomfortable questions about its own security. For decades, many European governments structured policies around the belief that a major war on the continent was improbable. Defence spending remained relatively low, military industries contracted, and economic integration was often viewed as a substitute for hard security considerations. The war in Ukraine has challenged those assumptions. Increasingly, European leaders are discussing deterrence, defence production and strategic autonomy with a seriousness not seen for decades.

The timing of these debates is particularly striking given the prominence of D-Day commemorations in this week’s news cycle. The ceremonies honour one of the defining moments of the twentieth century, yet they also serve as reminders that peace in Europe was never inevitable. The post-war order required institutions, alliances and political commitment. It was built deliberately, not automatically. Today’s discussions about NATO, European security and military preparedness reflect growing recognition that maintaining stability requires active effort rather than passive expectation.

In many ways, Europe is experiencing a psychological adjustment as significant as its strategic one. Entire generations of political leaders grew up in an environment where the possibility of a major war on the continent seemed remote. Economic integration became the dominant political language. Defence policy often occupied a secondary position. The return of geopolitical competition is forcing governments to revisit assumptions that have shaped public policy for decades. This process is not merely military or economic. It is cultural and political as well.

Beyond security, this week’s headlines also reveal another challenge facing the post-Cold War consensus: the growing contest over identity, migration and social cohesion. Comments surrounding migration in Europe, debates over national identity and the rise of extremist political movements all point toward a broader phenomenon visible across many democracies. Citizens are increasingly questioning political, economic and cultural arrangements that were once widely accepted.

The significance of the German mayoral runoff involving a neo-Nazi party member extends beyond local politics. It reflects wider frustrations, anxieties and divisions that have become increasingly visible across parts of Europe. Similar dynamics can be observed in different forms throughout the Western world. Concerns about migration, economic inequality, cultural change and political representation are influencing elections and reshaping political landscapes.

The Pope’s remarks in Spain highlight another dimension of this debate. Questions surrounding migration are no longer simply about border policy. They have become discussions about identity, values, demographic change and the future character of societies. These issues often generate strong emotions because they touch on fundamental questions regarding belonging and national purpose. As a result, they have become central political battlegrounds throughout much of the developed world.

What is particularly noteworthy is that these debates are occurring at the same time as growing concerns about security and economic stability. During much of the post-Cold War era, many societies assumed they could discuss identity, migration and social change within a relatively stable geopolitical environment. Today, those conversations are taking place against a backdrop of war in Europe, instability in the Middle East and intensifying competition between major powers. The result is a political atmosphere in which domestic and international concerns increasingly reinforce one another.

What makes these developments particularly significant is that they occur against a backdrop of declining trust in institutions. Governments, media organisations, international bodies and traditional political parties increasingly face scepticism from segments of the population. This does not necessarily mean institutions are collapsing, but it does mean they can no longer rely on the level of automatic legitimacy they may have enjoyed during earlier periods.

The political tensions visible in Senegal provide a useful reminder that these dynamics are not confined to Western democracies. Around the world, governments are confronting rising expectations, demographic pressures, economic challenges and demands for political accountability. While the specific circumstances differ from country to country, many societies are grappling with similar questions about governance, legitimacy and representation.

Technology has amplified these trends. Information moves instantly. Political controversies spread globally within hours. Citizens compare their governments with others more frequently than ever before. Social media platforms have created new opportunities for participation and accountability, but they have also accelerated polarisation and reduced the influence of traditional gatekeepers. Political systems designed for a slower information environment are struggling to adapt to the speed of modern communication.

Taken together, these stories suggest that the world may be entering a period defined less by a single geopolitical rivalry and more by the erosion of several assumptions that once provided a sense of stability. The belief that economic integration would steadily reduce geopolitical competition is under pressure. The belief that Europe had largely moved beyond major security threats is under pressure. The belief that globalisation would naturally produce political convergence is under pressure. Even the assumption that technological progress would necessarily generate social cohesion appears increasingly uncertain.

Importantly, this does not mean the post-Cold War era is ending overnight. International trade remains extensive. Global institutions continue to function. Alliances remain intact. Cooperation still occurs across numerous areas. Yet the confidence that characterised much of the period following 1991 appears noticeably weaker. Governments are planning for greater uncertainty. Businesses are reassessing risk. Citizens are questioning longstanding assumptions. Political systems are adapting to new pressures.

This is why the most important signal from this week’s headlines is not any individual event. It is the growing realisation that many of the ideas that shaped the international system for the past three decades are being tested simultaneously. Security, identity, globalisation, migration, political legitimacy and technological change are all being debated with renewed intensity.

The challenge facing governments is therefore larger than managing individual crises. It is navigating a transition in which old assumptions no longer provide the same certainty, while new frameworks have yet to fully emerge. Periods like this are often uncomfortable because they involve ambiguity. Political leaders must make decisions without clear precedents. Institutions must adapt while preserving legitimacy. Societies must balance continuity with change.

History suggests that such transitions rarely unfold smoothly. The decades preceding the First World War were marked by technological innovation, expanding trade and growing interconnectedness, yet they also contained tensions that many observers underestimated. The end of the Cold War likewise produced a period of optimism before new challenges emerged. History does not repeat itself precisely, but it often reminds us that political orders are not permanent. They require maintenance, adaptation and, occasionally, reinvention.

The coming decade may therefore be defined less by a single conflict or a single leader than by the search for a new equilibrium. Governments will need to determine how to balance openness with security, globalisation with resilience, technological innovation with social cohesion and national interests with international cooperation. None of these questions has a simple answer. Yet they increasingly dominate political debates across continents.

That may ultimately be the deepest connection between the stories appearing in this week’s headlines. Whether examining Iran, Ukraine, Europe, migration, political polarisation, or democratic tensions elsewhere in the world, each reflects societies attempting to adapt to changing realities. The old assumptions have not disappeared entirely, but they no longer command the confidence they once did.

The question is not whether the post-Cold War consensus is under pressure. The evidence increasingly suggests that it is. The more important question is what comes next. The answer will shape not only geopolitics, but the political, economic and social landscape of the twenty-first century.

And judging by this week’s headlines, that debate is already well underway.
