The United States was heavily involved in creating the United Nations in 1945 and drafting its charter. The United States continued to exert substantial clout in the organization after its founding, though there have been periods during which U.S. officials have met with significant opposition inside the United Nations, in Congress, and in American electoral politics, all of which produced struggles to gain support for America’s international policy goals. U.S. influence in the international organization has thus waxed and waned. The early postwar years witnessed the zenith of American prestige on the global stage. Starting in the mid- to late 1950s, as decolonization and the establishment of newly independent nations quickened, the United States began to lose influence in the United Nations owing to the spreading perception that its alliances with the European colonial powers placed it on the wrong side of history. As U.N. membership skyrocketed, the organization became more responsive to the needs and interests of the decolonizing states. During the 1970s and early 1980s, the American public responded to declining U.S. influence in the United Nations with calls to defund the organization and to pursue a unilateral approach to international challenges. The role of the United States in the United Nations was shaped by the politics of the Cold War competition with the Soviet Union. Throughout the nearly five decades of the Cold War, the United Nations served as a forum for the political and ideological rivalry between the United States and the Soviet Union, which frequently inhibited the organization from fulfilling what most considered to be its primary mission: the maintenance of global security and stability. After the collapse of the Soviet Union and the peaceful end of the Cold War, the United States enjoyed a brief period of unrivaled global hegemony. During this period, U.S. officials pursued a closer relationship with the United Nations and sought to use the organization to build support for its international policy agenda and military interventionism.
