The institutions built after 1945 are straining under the weight of a world they were not designed for.
What the Multilateral System Was Built For
The multilateral institutions created in the decade following 1945 — the United Nations, the Bretton Woods institutions, the GATT — were designed by the victors of the Second World War to address specific problems that the prior international order had failed to prevent: the protectionist spirals that deepened the Depression, the absence of collective security mechanisms that allowed the fascist advance to proceed unchecked, and the financial instability that produced the conditions for the rise of authoritarian movements. The institutions were solutions to those specific problems, designed by actors operating within the political economy of 1944–1945.
The problems those actors could not have designed for were the decolonisation of the majority of the world's population over the subsequent two decades, the emergence of new economic powers that were absent or subordinate at the founding, the end of the Cold War that had structured the political dynamics within which the institutions operated, and the rise of non-state actors, transnational challenges, and digital interconnection that the founding generation had no framework to anticipate. The multilateral system is being asked to manage a world that is categorically different from the one for which it was designed.
The Stress Points
The stress on the multilateral system manifests in specific and identifiable points. The Security Council veto system, designed to ensure great power commitment to collective security, now primarily functions to prevent the Council from acting on the security challenges of the current period. The WTO dispute resolution system, designed to enforce trade rules between economies of roughly comparable scale and similar models, is struggling to address the competitive challenges of state capitalism in economies that are simultaneously large and governed by different rules than the liberal trade model assumes. The IMF voting structure, designed to reflect the economic weight of 1944, underrepresents the economies that have grown most rapidly since.
The multilateral system's failures are not failures of implementation — they are failures of design meeting a world its designers did not anticipate. Reform requires not just improving the existing institutions but determining which of the problems they were designed to solve remain the right problems, and which new problems require institutions that have not yet been built.
