Cold War


The Cold War was the period of conflict, tension and competition between the United States and the Soviet Union and their respective allies from the mid-1940s until the early 1990s. Throughout the period, the rivalry between the two superpowers was played out in multiple arenas: military coalitions; ideology, psychology, and espionage; military, industrial, and technological developments, including the space race; costly defense spending; a massive conventional and nuclear arms race; and many proxy wars.
