Soviet Attack on Japan
Stalin had promised the Allies that he would attack Japan three months after Germany had been defeated. On August 9, he declared war as agreed, invading Manchuria, northern Korea, southern Sakhalin, and the Kurile Islands. In the same week, the Americans dropped atomic bombs on Hiroshima and Nagasaki. Faced with certain destruction, the Japanese surrendered on August 15.
