What two countries were primarily involved in the Cold War?

The Cold War was a period of geopolitical tension and ideological conflict that primarily involved the United States and the Soviet Union. This rivalry emerged after World War II and was characterized by mutual distrust, competition for global influence, and a significant arms race, including nuclear weapons. The United States, representing capitalist and democratic ideologies, opposed the Soviet Union, which promoted communism and state control over resources and enterprises.

Throughout this period, the two superpowers engaged in various forms of competition, including proxy wars, propaganda campaigns, and the space race. Their opposing political and economic systems laid the foundation for a global divide that defined much of the 20th century. Understanding this rivalry helps clarify many international relations and conflicts in the post-war era.
