The atomic bombings of Hiroshima and Nagasaki were nuclear attacks at the end of World War II against the Empire of Japan by the United States ordered by the U.S. President Harry S. Truman on August 6 and 9, 1945.
. These bombs had been developed in the Manhattan Project.
The bombs killed as many as 140,000 people in Hiroshima and 80,000 in Nagasaki by the end of 1945. In both cities, most of the dead people were civilians, or non-soldiers.
One reason why the bombs killed so many people is because a lot of Japanese houses were made of wood. When the bombs exploded, the wooden buildings caught fire, which spread quickly.
Six days after the explosion over Nagasaki, on August 15, Japan announced its surrender to the Allied Powers, signing the surrender paper on September 2, officially ending the Pacific War and World War II.
Some people say that the atomic bombs actually saved many lives, because an Allied invasion of Japan would kill more people on both sides. Allied generals believed that an invasion of Japan would have killed more than a million people on each side. Others say that the bombings were evil, not necessary, and a war crime. People still argue about this.
The bombings led, in part, to post-war Japan adopting Three Non-Nuclear Principles, forbidding that nation from nuclear armament.
