With Germany defeated, Stalin switched focus to the war with Japan, transferring half a million troops to the Far East. Stalin was pressed by his allies to enter the war and wanted to cement the Soviet Union's strategic position in Asia. On 8 August, in between the U.S. atomic bombings of Hiroshima and Nagasaki, the Soviet army invaded Japanese-occupied Manchuria and defeated the Kwantung Army. These events led to the Japanese surrender and the war's end. Soviet forces continued to expand until they occupied all their territorial concessions, but the U.S. rebuffed Stalin's desire for the Red Army to take a role in the Allied occupation of Japan.
