Final answer:
The Yalta Conference's decisions anticipated problems such as the Soviet Union's authoritarian influence in Eastern Europe and the division of Germany, which led to future tensions and the onset of the Cold War.
Step-by-step explanation:
The Yalta Conference decisions were influential in shaping the postwar world. Notably, the concessions made to Stalin by Roosevelt and Churchill had significant implications for Eastern Europe. The anticipated problems included the Soviet Union's dominance over Eastern European countries, which stemmed from Roosevelt's agreement to Soviet intervention in the Pacific War in exchange for Stalin's commitment to free elections and democratic governments in Eastern Europe—a promise he did not keep. Overall, these decisions lead to tensions that heralded the beginning of the Cold War era.
One of the chief outcomes of the Yalta Conference was the agreed division of Germany into zones occupied by the allies, which, although it aimed for a structured postwar plan, contributed to Germany's fragmentation and the eventual establishment of the two separate states of East and West Germany. This division was emblematic of the broader ideological split between the Western powers and the Soviet Union.
The Yalta Conference laid ground for multiple contentious issues, such as Stalin's later retraction of his agreement to allow free elections, leading to an autocratic Soviet influence in Eastern Europe. Furthermore, the decision to demilitarize and denazify Germany, the matter of reparations, and the international pursuits of both the United States and the Soviet Union were major contributors to the Cold War dynamic.
