when did the soviets declared war on japan
Soviet–Japanese War The Soviet–Japanese War (Russian: Советско-японская война; Japanese: ソ連対日参戦, "Soviet Union entry into war against Japan") was a military conflict within the Second World War beginning soon after midnight on August 9, 1945, with the Soviet invasion of the Japanese puppet state of Manchukuo. The Soviets and Mongolians terminated Japanese control of Manchukuo, Mengjiang (Inner Mongolia), northern Korea, Karafuto, and the Chishima Islands. The defeat of Japan's Kwantung Army helped in the Japanese surrender and the termination of World War II.[7][8] The Soviet entry into the war was a significant factor in the Japanese government's decision to surrender unconditionally, as it made apparent the Soviet Union would no longer be willing to act as a third party in negotiating an end to hostilities on conditional terms.[1][9][10][11][12][13][14][15]
Surrender of Japan On August 6, 1945, at 8:15 AM local time, the United States detonated an atomic bomb over the Japanese city of Hiroshima. Sixteen hours later, American President Harry S. Truman called again for Japan's surrender, warning them to "expect a rain of ruin from the air, the like of which has never been seen on this earth." Late in the evening of August 8, 1945, in accordance with the Yalta agreements, but in violation of the Soviet–Japanese Neutrality Pact, the Soviet Union declared war on Japan, and soon after midnight on August 9, 1945, the Soviet Union invaded the Imperial Japanese puppet state of Manchukuo. Later in the day, the United States dropped a second atomic bomb, this time on the Japanese city of Nagasaki. Following these events, Emperor Hirohito intervened and ordered the Supreme Council for the Direction of the War to accept the terms the Allies had set down in the Potsdam Declaration for ending the war. After several more days of behind-the-scenes negotiations and a failed coup d'état, Emperor Hirohito gave a recorded radio address across the Empire on August 15. In the radio address, called the Jewel Voice Broadcast (玉音放送, Gyokuon-hōsō), he announced the surrender of Japan to the Allies.

Soviet Union in World War II Stalin directed the Red Army to move rapidly in a broad front into Germany because he did not believe the Western Allies would hand over territory they occupied, while he made the overriding objective capturing Berlin.[169] After successfully capturing Eastern Prussia, three Red Army fronts converged on the heart of Eastern Germany, with one of the last pitched battles of the war putting the Soviets at the virtual gates of Berlin.[170] By April 24, Berlin was encircled by elements of two Soviet fronts,[171] one of which had begun a massive shelling of the city on April 20 that would not end until the city's surrender.[172] On 30 April, Hitler and Eva Braun committed suicide, after which Soviet forces found their remains, which had been burned at Hitler's directive.[173] German forces surrendered a few days later. Some historians argue that Stalin delayed the last final push for Berlin by two months in order to capture other areas for political reasons, which they argue gave the Wehrmacht time to prepare and increased Soviet casualties (which exceeded 400,000), though this is contested by other historians.[174]
