Final answer:
The rift between the USA and the Soviet Union became well known during the Potsdam Conference in 1945, which revealed significant disagreements about post-war Europe. The attitudes of leaders and their decisions at this conference marked the escalation of tensions between the two superpowers. Though earlier conferences like Yalta provided initial cooperation, Potsdam represented a shift towards open hostility.
Explanation:
The Rift Between the USA and Soviet Union
The development of the rift between the USA and the Soviet Union became well known during the Potsdam Conference, which was held in July-August 1945. This conference was significant in shaping post-World War II Europe and highlighted the growing tensions between the two superpowers.
While the Yalta Conference (February 1945) initially showcased a semblance of cooperation among the allies, the attitudes of the leaders, particularly those of President Harry Truman and Premier Joseph Stalin, shifted at Potsdam. During this later conference, disagreements over the administration of Germany and Eastern Europe emerged, leading to a more adversarial relationship. The Tehran Conference (1943) and the Malta Conference (1989) are less critical in the immediate development of this rift, as the former occurred before much of the post-war landscape was established, while the latter dealt with Cold War dynamics decades later.
In conclusion, it was at the Potsdam Conference that the ideological split began to solidify, setting the stage for the long-standing conflict known as the Cold War.
