Changes

By the end of April, the new administration clashed with the Soviets over their influence in Eastern Europe, and over the United Nations. Alarmed at the perceived lack of cooperation on the part of the Soviets, many Americans began to criticize Roosevelt’s handling of the Yalta negotiations. To this day, many of Roosevelt’s most vehement detractors accuse him of “handing over” Eastern Europe and Northeast Asia to the Soviet Union at Yalta despite the fact that the Soviets did make any substantial concessions.

The "Big Three" conferences during the war helped the allies to coordinate with each other and against Germany and Japan. While the conferences allowed the three countries to cooperate with each other, they did not successfully iron out what the post=war world would look like. Unfortunately, the powers would have never been able to come to any meaningful agreements about post-war Europe. Additionally, the Soviet Union had little patience for American and British interference in Eastern Europe. Neither Britain nor the United States was willing to go to war with the USSR as soon as World War II ended to limit the Soviet's territorial aspirations.
