How did the end of World War 2 politically affects both the US and the Soviets union?

The end of World War II marked the emergence of the United States and the Soviet Union as superpowers, leading to a bipolar world order characterized by ideological conflict. The U.S. promoted capitalism and democracy, while the Soviet Union sought to expand communism, resulting in the Cold War. This rivalry influenced global politics, leading to military alliances such as NATO and the Warsaw Pact, and shaping international relations for decades. Additionally, decolonization movements gained momentum as both superpowers sought to extend their influence in newly independent nations.
