Which event is associated with the establishment of a post-war world organization by Roosevelt, Churchill, and Stalin?

The Yalta Conference is the event associated with the establishment of a post-war world organization by President Franklin D. Roosevelt, Prime Minister Winston Churchill, and Premier Joseph Stalin. This conference, held in February 1945, was critical as it addressed the reorganization of post-war Europe and the future of Germany following the anticipated defeat of Nazi Germany.

At Yalta, the leaders discussed key issues, including the formation of the United Nations, which aimed to promote international cooperation and prevent future conflicts. This concept was a significant outcome of the meeting, marking the collaborative effort of the major Allied powers to establish a framework for maintaining peace after World War II.

In contrast, the Potsdam Conference, which took place later in July-August 1945, focused on specific issues related to the administration of Germany and was held after the war in Europe had ended. The Geneva Conference primarily dealt with issues in Southeast Asia, particularly regarding the future of Vietnam, while the Paris Peace Conference involved negotiations for peace treaties after World War I. Thus, the focus on the formation of a world organization distinctly aligns with the discussions at the Yalta Conference.
