[1]  [DOC] The Cold War (1947–1953) is the period within the Cold War from the Truman Doctrine in 1947 to the conclusion of the Korean War in 1953. The Cold War began almost immediately following World War II and lasted through most of the 20th century. Political relations between the USA, Britain, Canada and the USSR were tainted within days of VJ-Day when cipher clerk Igor Gouzenko defected from the Soviet embassy in the Canadian capital, offering documentary proof of two wartime networks of Soviet spies in North America, one aimed at the Manhattan Project. In the next five years spies Julius and Ethel Rosenberg and Klaus Fuchs were exposed and British diplomats Guy Burgess and Donald Maclean defected to the Soviet Union. [END]
