Triumphantly completing the Great Patriotic War against Nazi Germany and the Soviet people under the leadership of the Communist Party began to heal severe wounds caused by a cruel and relentless enemy. However, the security of the Soviet Union threatened to further imperialist Japan. While in 1941-1945, Japan did not dare to start a war against the Soviet Union on the side of Nazi Germany, Japanese imperialism remained the worst enemy of the Soviet Union. October 30, 1943, Stalin made the final decision to join the war against Japanese aggression. At a Kremlin reception after the completion of the Moscow Conference of Foreign Ministers, Stalin confided to Cordell Hull US Secretary of State, that the Soviet Government considered the situation in the Far East, and decided immediately after the end of the war in Europe, when the allies will defeat Hitler Germany, to take part in the war against the common enemy - the Japanese. Stalin, wrote in his memoirs, Hull, made this statement, "confident, completely selflessly without asking anything in return." The diplomatic move of Stalin, of course, pushed England and the United States, especially interested in the defeat of Japan, the opening of a second front in Europe.
