Read this excerpt from President Harry Truman’s 1946 State of the Union speech:

Long before our enemies surrendered, the foundations had been laid on which to continue this unity in the peace to come. The Atlantic meeting in 1941 and the conferences at Casablanca, Quebec, Moscow, Cairo, Tehran, and Dumbarton Oaks each added a stone to the structure.

Early in 1945, at Yalta, the three major powers broadened and solidified this base of understanding. There fundamental decisions were reached concerning the occupation and control of Germany. There also a formula was arrived at for the interim government of the areas in Europe which were rapidly being wrested from Nazi control. This formula was based on the policy of the United States that people be permitted to choose their own form of government by their own freely expressed choice without interference from any foreign source.

At Potsdam, in July 1945, Marshal Stalin, Prime Ministers Churchill and Attlee, and I met to exchange views primarily with respect to Germany. As a result, agreements were reached which outlined broadly the policy to be executed by the Allied Control Council. At Potsdam there was also established a Council of Foreign Ministers which convened for the first time in London in September. The Council is about to resume its primary assignment of drawing up treaties of peace with Italy, Rumania, Bulgaria, Hungary, and Finland.

In addition to these meetings, and, in accordance with the agreement at Yalta, the Foreign Ministers of Great Britain, the Soviet Union, and the United States conferred together in San Francisco last spring, in Potsdam in July, in London in September, and in Moscow in December. These meetings have been useful in promoting understanding and agreement among the three governments.
