What did the big three make decisions on?

The "Big Three" refers to the leaders of the United States, the United Kingdom, and the Soviet Union during World War II—Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin. They made crucial decisions regarding military strategy, post-war territorial arrangements, and the establishment of international organizations, such as the United Nations, to promote peace and cooperation. Their agreements shaped the post-war order and influenced global politics for decades. Key conferences, such as Yalta and Potsdam, were pivotal in these decision-making processes.
