Potsdam Conference begins

The final “Big Three” meeting between the United States, the Soviet Union and Great Britain takes place towards the end of World War II. The decisions reached at the conference ostensibly settled many of the pressing issues between the three wartime allies, but the meeting was also marked by growing suspicion and tension between the United States and the Soviet Union.

On July 17, 1945, U.S. President Harry S. Truman, Soviet leader Joseph Stalin, and British Prime Minister Winston Churchill met in the Berlin suburb of Potsdam to discuss issues relating to postwar Europe and plans to deal with the ongoing conflict with Japan. By the time the meeting began, U.S. and British suspicions concerning Soviet intentions in Europe were intensifying. Russian armies occupied most of Eastern Europe, including nearly half of Germany, and Stalin showed no inclination to remove his control of the region. Truman, who had only been president since Franklin D. Roosevelt died three months earlier, arrived at the meeting determined to be “tough” with Stalin. He was encouraged in this course of action by news that American scientists had just successfully tested the atomic bomb. 

The conference soon bogged down on the issue of postwar Germany. The Soviets wanted a united but disarmed Germany, with each of the Allied powers determining the destiny of the defeated power. Truman and his advisors, fearing the spread of Soviet influence over all Germany–and, by extension, all of western Europe–fought for and achieved an agreement whereby each Allied power (including France) would administer a zone of occupation in Germany. Russian influence, therefore, would be limited to its own eastern zone. The United States also limited the amount of reparations Russia could take from Germany. Discussion of the continuing Soviet occupation of Poland floundered.

When the conference ended on August 2, 1945, matters stood much where they had before the meeting. There would be no further wartime conferences. Four days after the conference concluded, the United States dropped an atomic bomb on Hiroshima in Japan; on August 9, another bomb was dropped on Nagasaki. World War II officially came to an end on August 14, 1945.
