In February 1945, the 'Big Three' Allied leaders—Winston Churchill, Franklin D. Roosevelt, and Joseph Stalin—met at Yalta to discuss the final defeat of Germany and the postwar reorganization of Europe. They agreed that Germany would be divided into four occupation zones (British, French, American, and Soviet) and that Berlin, though deep in the Soviet zone, would also be divided. Stalin agreed to allow 'free and unfettered elections' in Poland and other Eastern European nations liberated by the Red Army. They also discussed the creation of the United Nations and the Soviet entry into the war against Japan. However, the failure to clearly define the terms of these elections and the growing distrust between the West and the USSR would eventually lead to the start of the Cold War.
