Truman decided to drop the atomic bomb on Hiroshima, Kokura, Niigata, and Nagasaki because Japan attacked Pearl Harbor without warning. This occurrence happened at the end of WWII. America, China, and the United Kingdom joined forces to gain surrender from the Japan armed forces. The alliance, also called the “Manhattan Project,” tested an atomic device, and were able to make weapons based on two alternate designs. One was a uranium gun-type atomic bomb, and the other was a plutonium implosion-type atomic bomb. The 509th composite group of the U.S. Armed Air Forces stored the bombs. The 2 bombs that the U.S. dropped on two separate dates in August of 1945 are the only active deployments of nuclear weapons in war to date.

The 2 bombs that the U.S. dropped on two separate dates in August of 1945 are the only active deployments of nuclear weapons in war to date. The bomb order was drafted by General Groves, and was approved by Truman, General of War. The first atomic bomb was dropped on August 6th, 1945. The bomb weighed 9,000 pounds. It exploded within 100 feet of the target. The fireball was 18 feet across, and its center was as hot as the surface of the sun. In the center of the bomb people became nothing, near the center there was no sound. The light from the bomb flashed a painful bright white. Within 9 seconds, 100,000 people were killed or doomed, and another 100,000 more injured. Within 9 seconds the city caught fire, a cloud of smoked raised 40,000 feet high. Most doctors died in the bombing, and between 3 and 10,000 people came to the hospitals for help each day. 2,000 of them died daily.
