The idea
Between 1945 and 1948 the USSR consolidated control over Eastern Europe. Soviet forces occupied much of the region at the end of the war, and communist governments loyal to Moscow were established, often called satellite states. The conferences at Yalta (February 1945) and Potsdam (July–August 1945) set out agreements on the future of Germany and Europe, but growing disagreement, especially over Poland and Germany, widened the split. The USA and its allies responded with containment: the Truman Doctrine (1947) offered support to states resisting communism, and the Marshall Plan (1947) provided economic aid to rebuild Western Europe. These responses deepened the division of Europe. A strong answer links each Soviet action to a specific Western response and shows how the conferences contributed to mistrust.
