Who was the period of political tension following World War 2?

The period of political tension following World War II is commonly referred to as the Cold War, which lasted from roughly 1947 to 1991. This era was characterized by the ideological conflict between the United States and its allies, promoting capitalism and democracy, and the Soviet Union and its satellite states, advocating communism. The Cold War involved various forms of indirect confrontation, including military alliances, proxy wars, and an arms race, but it did not escalate into direct military conflict between the superpowers. Key events during this time included the Korean War, the Cuban Missile Crisis, and the Vietnam War.
