when us dropped bomb on hiroshima and nagasaki
Atomic bombings of Hiroshima and Nagasaki During the final stage of World War II, the United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. The United States dropped the bombs after obtaining the consent of the United Kingdom, as required by the Quebec Agreement. The two bombings killed 129,000â€“226,000 people, most of whom were civilians. They remain the only use of nuclear weapons in the history of warfare.

World War II World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's countries—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of total war, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources.
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, after its April 1945 denunciation of the Soviet–Japanese Neutrality Pact, and in accordance with the Yalta agreements, the Soviet Union declared war on Japan. Shortly 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.
