Final answer:
At the Yalta Conference, Stalin reaffirmed his commitment to enter the war against Japan three months after Germany's defeat. Other commitments included free elections in Eastern Europe and support for the United Nations, though his adherence to these commitments, particularly regarding elections, was questionable in the aftermath.
Step-by-step explanation:
Yalta Agreement and Stalin's Commitment
The Yalta Agreement reaffirmed Stalin's commitment to enter the war against Japan three months after the defeat of Germany. This agreement took place at the Yalta Conference in February of 1945, where leaders of the United Kingdom, United States, and the Soviet Union met to discuss postwar plans. Among these, Stalin agreed to free elections in Eastern European nations and promised to join the United Nations. Although Stalin made such commitments at Yalta, his subsequent actions reflected a divergence from these agreements, notably in allowing truly free elections in Eastern Europe.
Roosevelt's agenda for the meeting with Stalin at Yalta was multifaceted. It included securing Soviet support in the U.S. Pacific War against Japan, as well as support for the establishment of the United Nations. Churchill sought free elections and democratic governments in eastern and central Europe, specifically Poland, while Stalin demanded a Soviet sphere of influence in the region. Ultimately, Yalta agreements largely favored Soviet interests in Eastern Europe. The Yalta Conference was essential in shaping the geopolitical landscape of postwar Europe and set the stage for future international tensions that culminated in the Cold War.
