Cold War Overview
The Cold War was a sustained state of political and military tension between powers in the Western Bloc (the United States with NATO and others), and powers in the Eastern Bloc, (the Soviet Union (USSR) and its allies in Warsaw Pact). Historians have not fully agreed on the dates, but 1947–1991 is common. It was "cold" because there was no large-scale fighting directly between the two sides, although there were major regional wars in Korea and Vietnam. The Cold War split the temporary wartime alliance against Nazi Germany, leaving the USSR and the US as two superpowers with profound economic and political differences over capitalism and democracy. A deliberately neutral grouping arose with the Non-Aligned Movement founded by Egypt, India, and Yugoslavia; this faction rejected association with either the US-led West or the Soviet-led East.
