title: Cold War text: Cold War The Cold War was a period of geopolitical tension between the Soviet Union with its satellite states (the Eastern Bloc), and the United States with its allies (the Western Bloc) after World War II. A common historiography of the conflict begins with 1946, the year U.S. diplomat George F. Kennan's "Long Telegram" from Moscow cemented a U.S. foreign policy of containment of Soviet expansionism threatening strategically vital regions, and ending between the Revolutions of 1989 and the 1991 collapse of the USSR, which ended communism in Eastern Europe. The term "cold" is used because there was no large-scale title: Origins of the Cold War text: Origins of the Cold War The Origins of the Cold War involved the breakdown of relations between the Soviet Union versus the United States, Great Britain and their allies in the years 1945–1949. From the American-British perspective, first came diplomatic confrontations stretching back decades, followed by the issue of political boundaries in Central Europe and political non-democratic control of the East by the Soviet Army. Then came economic issues (especially the Marshall Plan) and then the first major military confrontation, with a threat of a hot war, in the Berlin Blockade of 1948–1949. By 1949, the lines were sharply drawn title: Origins of the Cold War text: control of an Eastern Bloc of Soviet satellite states. In World War I, Britain, France and Russia had been allies from the start in 1914, and the U.S. joined in April 1917. The Bolsheviks seized power in Russia in November 1917 but German armies advanced rapidly deep into the country. The Allies responded with an economic blockade against all of Russia.

In the eyes of some Allies, Russia now was helping Germany win title: Origins of the Cold War text: and the Cold War was largely in place in Europe. Outside Europe, the starting points vary in the late 1940s or early 1950s. Events preceding World War II and even the Russian Revolution of 1917, underlay older tensions between the Soviet Union, European countries and the United States. A series of events during and after World War II exacerbated tensions, including the Soviet–German pact in 1939, the Anglo-Americans repeated postponement of an amphibious invasion of German-occupied Europe, the Western allies' support of the Atlantic Charter, Soviet rejection of decisions about Eastern European democracy made in wartime conferences and the Kremlin's title: Cold War text: the U.S. occupation directive JCS 1067, which was in effect for over two years, and was enthusiastically supported by Stalin. It directed the U.S. forces of occupation to "...take no steps looking toward the economic rehabilitation of Germany". Some historians have argued that the Cold War began when the US negotiated a separate peace with Nazi SS General Karl Wolff in northern Italy. The Soviet Union was not allowed to participate and the dispute led to heated correspondence between Franklin Roosevelt and Stalin.
