The ideological conflict that characterized the Cold War between two superpowers was primarily between capitalism and communism. The United States, advocating for capitalism and democratic governance, faced off against the Soviet Union, which promoted a communist ideology. This rivalry manifested in various forms, including political tensions, economic competition, and military confrontations, such as the Arms Race. The Cold War influenced global alliances, leading to proxy wars and a divided world. This era saw significant developments in technology and military power while shaping international relations and foreign policies for decades.
