Post-Cold War US foreign policy refers to the strategies and actions taken by the United States in international relations after the end of the Cold War, which concluded with the dissolution of the Soviet Union in 1991. This period was marked by a shift towards promoting democracy, globalization, and interventionist policies, significantly influencing the global political landscape. As the US emerged as the world's sole superpower, it sought to redefine its role and address new challenges such as terrorism, regional conflicts, and humanitarian crises.
