The United States played a leading role in the Bretton Woods and Yalta conferences, during which agreements were signed on new international financial institutions and Europe's postwar reorganization. As an Allied victory was achieved in Europe, a 1945 international conference held in San Francisco produced the United Nations Charter, which became active after the war. The United States developed the first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945; the Japanese subsequently surrendered on September 2, ending World War II.
