Atomic bombings of Hiroshima and Nagasaki
 Some people say that the atomic bombs actually saved many lives. Without the bombs, the Allies would have had to invade Japan to end the war. More people would have been killed on both sides in a full battle in Japan. 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 and were not necessary. They also call the bombings a war crime because so many civilians were killed, many of them with slow, painful deaths.
