What was an impact of world war 2 on American politics?

World War II significantly transformed American politics by solidifying the United States' role as a global superpower and leading to the establishment of a more interventionist foreign policy. The war catalyzed the expansion of federal government powers, as it required increased economic mobilization and coordination. Domestically, it spurred civil rights movements, as returning veterans and marginalized groups demanded equal rights and opportunities. Additionally, the post-war period saw the rise of the Cold War, shaping U.S. political discourse around anti-communism and international alliances.
