Describing the Yalta Conference, FDR once said, “It is permitted in time of great danger to walk with the devil until you have crossed the bridge.” Held from February 4-11, 1945, the conference was convened by Roosevelt, Churchill, and Stalin to wrap up WWII in Europe. Almost from the start, Stalin ignored the agreement as he expanded Soviet influence over Eastern and Western Europe, precipitating a chillier kind of war.
