After the war, Churchill's party lost the election and he was no longer Prime Minister. He was still a major leader in the government, however. He was again elected Prime Minister in 1951. He served the country for many years and then retired. He died on January 24, 1965. Churchill was concerned about the Soviet Union and the Red Army. He felt they were just as dangerous as Hitler now that the Germans were defeated. He was right as soon after World War II ended, the Cold War between the Western nations of NATO (such as Britain, France, USA) and communist Soviet Union began.
