Which conference in February 1945, attended by Churchill, Roosevelt, and Stalin, set terms for postwar Europe and led to the UN Security Council structure?

• A. Potsdam Conference
• B. Tehran Conference
• C. Geneva Conference
• D. Yalta Conference

Answer: (D)

This question tests how wartime diplomacy shaped the postwar world and the creation of the United Nations. The February 1945 meeting in Yalta brought Churchill, Roosevelt, and Stalin together to decide how Europe would be reorganized after the war, including how Germany would be occupied and how borders and governments in Eastern Europe would be arranged. At the same time, they agreed on a framework for the future international order, endorsing a Security Council with permanent members and veto power—an arrangement that would become a central feature of the UN Charter and help govern postwar peacekeeping. The timing and the participants clearly point to this conference as the moment that linked postwar terms for Europe with the structure of the United Nations. Other conferences occurred at different times or focused on different issues, so they don’t fit the specific February 1945 meeting described.
