The End of an Era: Post-War Order Collapses Under New Realities
The world order established after World War II, long underpinned by American leadership and a framework of rules-based cooperation, is now facing an unprecedented collapse. In a stark declaration at the Davos summit, Canadian Prime Minister Mark Carney captured the sentiment of many global elites, stating that the era of US-dominated western order has definitively ended. This shift marks a profound rupture in international relations, driven by changing dynamics and leadership styles.
A System Built on Interdependence No Longer Holds
The postwar architecture, designed to promote peace through economic interdependence and shared security, has been fundamentally undermined. The United States, once the architect and enforcer of this system, has increasingly abandoned its principles. Donald Trump's presidency accelerated this trend, with his administration viewing global alliances as burdens rather than benefits, accusing other nations of free-riding on American security and market openness.
Carney's speech highlighted the dangers of this new reality, noting that great powers now wield economic integration as a weapon, using tariffs, financial systems, and supply chains to coerce and exploit. This represents a dramatic departure from the mutual benefits once touted as the cornerstone of global integration.
Global Reactions and the Search for Alternatives
The analysis is gaining traction worldwide. At the Munich Security Conference, German Chancellor Friedrich Merz echoed Carney's concerns, warning that the international order based on rights and rules is being destroyed, with American leadership potentially already lost. European leaders, including French President Emmanuel Macron and British Prime Minister Keir Starmer, have called for Europe to develop its own geopolitical and hard power capabilities to navigate this uncertain landscape.
However, the question remains: what comes next? Is it feasible to construct a new liberal, multilateral order resilient enough to withstand pressure from competing superpowers like the US and China? Carney proposed a third path where countries combine efforts rather than compete for favor, but experts are skeptical.
The Challenges of Building a New Order
Jorge Castañeda, Mexico's former foreign minister, dismissed the viability of such a third path, arguing that few nations have the capacity to decouple from Washington's trajectory. Instead, countries are engaging in uncoordinated efforts to protect themselves, forming new trade pacts and strategic agreements. For instance, the European Union and India recently signed a free-trade agreement after 20 years of stalemate, partly motivated by fears of Trump's tariffs.
Yet, building concrete alliances remains difficult. The EU's trade deal with Mercosur faced legal challenges from European farmers, illustrating how domestic interests can derail international cooperation. Moreover, losing American leadership means forfeiting valuable public goods, such as the dollar as a global currency, US treasury bonds for wealth storage, and a regime of collective security that managed conflicts from the Balkans to the South Pacific.
Dependence and the Limits of Autonomy
Many nations find themselves too dependent on the US to fully break away. Japan relies heavily on American security guarantees, while the EU, despite its economic size, depends on US support to counter Russian ambitions in Ukraine. Nato chief Mark Rutte bluntly stated that Europe cannot defend itself without the US, highlighting the enduring military and strategic ties.
Even Canada, despite its efforts to chart an independent course, sends two-thirds of its exports to the US, linking its prosperity inextricably to its southern neighbor. This economic entanglement complicates any move toward true autonomy.
Hopes for Restoration and the Reality of Rupture
Some leaders cling to the hope of restoring the old order. Wolfgang Ischinger of the Munich conference advocated for a constructive transatlantic reset, while Democrats in the US, like California Governor Gavin Newsom, frame Trump's administration as a temporary lapse. However, Carney's assessment that this represents a rupture, not a transition, seems more accurate. The global system has shifted irreversibly, with power dynamics taking precedence over cooperative frameworks.
A World Without Clear Leadership
China, the other global superpower, shows little interest in assuming the mantle of liberal multilateral leadership. Its mercantilist policies and closed markets undermine trust, and it appears content to let the postwar order crumble, perceiving it as hostile to its interests. In this vacuum, the world risks fragmenting into ad-hoc deals and transactional alliances, driven by pragmatism rather than shared values.
Alexander Stubb, President of Finland, describes this as a new world of disorder, comparable to historical watersheds like the world wars. He advocates for rebuilding global institutions to give more voice to the global south, but success hinges on US willingness to participate in a less dominant role—a prospect that seems unlikely.
The Consequences of a Disorderly World
The likely outcome is a system with no agreed-upon guidelines for trade, finance, or human rights, potentially splitting the world into competing spheres of influence around the US and China. Weaker nations may become vassal states, while others, like Brazil and India, might play powers against each other. This new reality will stifle trade, raise costs, and force countries to face threats alone, losing economies of scale and common insurance against risks.
As Carney noted, echoing Thucydides, we may enter an era where the strong do what they can, and the weak suffer what they must. This shift away from rules-based multilateralism threatens global stability and prosperity, marking a regrettable departure from a system that, despite its flaws, offered a better way to organize world affairs.
