How far each side went on the battlefields was predetermined at the conferences. Interestingly enough, Joe Stalin had the best sense of humor of any of them, and Truman and Churchill liked him personally.

"Conferences involving, President Franklin D. Roosevelt, President Harry S. Truman, Prime Minister Winston S. Churchill, Soviet leader Joseph Stalin, French leader Charles de Gaulle, French leader Henri Giraud, and Generalissimo Chiang Kai-shek.

"During World War II, President Franklin D. Roosevelt and Prime Minister Winston S. Churchill formulated allied grand strategy at a series of high-level conferences held in Washington, DC, Casablanca, Quebec, Cairo, Tehran, Yalta, and Potsdam. At the Tehran, Yalta, and Potsdam conferences, the Russian leader, Joseph Stalin, also played a major role. Under policy guidance from their national leaders, the newly formed US Joint Chiefs of Staff and their British counterparts, known collectively as the Combined Chiefs of Staff, hammered out the military details of allied strategy."
