The Situation in West Berlin
In 1948, Berlin was the divided capital of a divided country. The eastern sector of the city was occupied by the Soviet Union and the three western sectors by the United States, Great Britain, and France. As wartime Allies, these nations had defeated Nazi Germany. In June 1948, following a dispute with the three western powers over currency reform, the Soviet Union established a blockade around Berlin. The capital was located deep within Soviet-controlled eastern Germany. By sealing off the roads linking Berlin to western Germany, the Soviets hoped they could force the Americans, British, and French to leave their sectors of the city.
Berlin's two and a half million inhabitants faced the prospect of privation and even starvation as their food and other supplies ran out. And President Truman faced a stark choice: either abandon the city to the Soviets or risk a military confrontation that could lead to World War III.
