The Cold War was the time period from 1945 to 1990 where there was constant tension and struggle between the United States and its allies and the Soviet Union and its allies.Actual military conflict never occurred, but there were great amounts of hostility and rivalry between the two sides, as well as intense clashes of economic and diplomatic policies.
