Soviet Union leader Joseph Stalin broke the Yalta agreement by failing to give his promise of free elections to Eastern Europe. Instead, he established governments that were dominated by the Soviet Union. American critics claimed that United States President Franklin Roosevelt, who had died two months after the Yalta Agreement, had compromised the agreement with the Soviet Union.
The Yalta Agreement involved Roosevelt, Stalin and Winston Churchill, the British prime minister. The meeting occurred in January of 1945 as the World War II came to an end. The three leaders agreed that Germany was to surrender and to set up a zone of participation to be run by Russia, Britain, the U.S and France. Stalin agreed to enter the Asian war against Japan and to give free elections to Eastern Europe.
