Why were the US and the soviet union primarily involved in the cold war?

The Cold War primarily stemmed from ideological differences between the United States and the Soviet Union, with the U.S. promoting capitalism and democracy, while the U.S.S.R. advocated for communism and a one-party state. Following World War II, both superpowers emerged as global leaders and sought to expand their influence, leading to a power struggle characterized by political tension, military rivalry, and proxy wars. Key events, such as the Berlin Blockade and the Cuban Missile Crisis, further intensified their competition, creating a climate of fear and suspicion that defined the era. Ultimately, the Cold War was a multifaceted conflict rooted in competing worldviews and the desire for geopolitical dominance.
