In February 1945, when Roosevelt, Churchill and Stalin gathered at Yalta, an Ally victory emerged in Europe. After liberating France and Belgium from Nazi occupation, the Allies threatened the German border; To the east, Soviet troops had repelled the Germans from Poland, Bulgaria and Romania and are less than 40 miles from Berlin.

But as his troops occupied much of Germany and Eastern Europe, Stalin succeeded in effectively ratifying the concessions he had made to Yalta and putting pressure on his advance on Truman and Churchill (replaced by Prime Minister Clement Atlee in the middle of the conference). In March 1946, barely a year after the Yalta Conference, Churchill delivered his famous speech in which he declared that an “iron curtain” had fallen on Eastern Europe, marking the definitive end of cooperation between the Soviet Union and its Western allies and the beginning of the Cold War.

Leahy, the Yalta language was so vague that the Soviets would be able to “stretch it from Yalta to Washington without ever breaking it technically.”  A Soviet condition for a declaration of war in Japan was an official recognition of China`s Mongolian independence (the Mongolian People`s Republic was a Soviet satellite state from early 1924 until World War II).
