U.S imperialism, or American Imperialism, is a stage of imperialism that is characterised by unipolarity and the hegemony of global finance capital, enforced by the Deep State of the United States. U.S imperialism is not static and has evolved with time. After the Second World War and throughout the Cold War, U.S imperialism had the characteristic of propping up banana republics and anti-Communist client states. After the defeat of the Soviet Union, as the U.S emerged as the sole superpower, U.S imperialism is marked by a unipolar hegemonic order. However, since 2020, U.S imperialism has been waning due to internal and external challenges.
The most infamous cases of U.S imperialism come from the recent War on Islam, justified by "counterterrorism," and contemporary escalations against Russia, China, Iran and the Democratic People's Republic of Korea (or North Korea).
