Changes

The Soviets, who had long been pushing the Allies to open a second front, agreed to launch another major offensive on the Eastern Front that would divert German troops away from the Allied campaign in northern France. Stalin also agreed in principle that the Soviet Union would declare war against Japan following an Allied victory over Germany. In exchange for a Soviet declaration of war against Japan, Roosevelt conceded to Stalin’s demands for the Kurile Islands and the southern half of Sakhalin, and access to the ice-free ports of Dairen (Dalian) and Port Arthur (Lüshun Port) located on the Liaodong Peninsula in northern China. The exact details concerning this deal were not finalized, however, until the Yalta Conference of 1945.

====Questions regarding post-war Europe are Discussed====

===Conclusion===

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.
