The Cold War was a battle between the Comintern (all communist countries) and NATO (the US alliance) a nuclear disagreement occurred which enabled the United states to declare war on Russia, the war went on for years unsure which side was really winning. The Cold War was a period of ideological and geopolitical tension between the United States and the Soviet Union, and their respective allies, the Western Bloc and the Eastern Bloc, after World War II. Historians do not fully agree on its starting and ending points, but the period is generally considered to span the 1947 Truman Doctrine (12 March 1947) to the 1991 Dissolution of the Soviet Union (26 December 1991).
During World War II, the United States and the Soviet Union fought together as allies against the Axis powers. However, the relationship between the two nations was a tense one. Americans had long been wary of Soviet communism and concerned about Russian leader Joseph Stalin’s tyrannical rule of his own country. For their part, the Soviets resented the Americans’ decades-long refusal to treat the USSR as a legitimate part of the international community as well as their delayed entry into World War II, which resulted in the deaths of tens of millions of Russians. After the war ended, these grievances ripened into an overwhelming sense of mutual distrust and enmity.
