The leaders of the United States, the Soviet Union and Britain met three times during the war. What were they?
【正确答案】：The leaders of the United States, the Soviet Union and Britain met three times during the war. The first summit was held at Teheran in November 1943. At the conference it was decided that a large-scale attack on the south of France would be launched in May 1944, which was codenamed Overlord. The second conference was held in Yalta in February 1945. The conference actually approved a re-division of postwar sphere of influence among the three powers and decided on the setting-up of a world organization the United Nations. It was also at the conference that Roosevelt had the promise of Stalin that the Soviet Union would declare war on Japan three months after the defeat of Germany. The third conference was held at Potsdam, outside Berlin, during July and August 1945. The conference confirmed the temporary division of Europe agreed to at Yalta. At the same time, the conference showed there were great differences among the three powers. Most of these differences were not solved at the conference, which later led to tension between the United States and the Soviet Union.
