What did the atomic bomb do in World War 2?

Answer 1

While Allied military leaders planned for invasion, scientists offered another way to end the war. Since the early 1900s, scientists had understood that matter, made up of atoms, could be converted into pure energy. In military terms, this meant that, by splitting the atom, scientists could create an explosion far more powerful than any yet known. During the war, Allied scientists, some of them German and Italian refugees, raced to harness the atom. In July 1945, they successfully tested the first atomic bomb at Alamogordo, New Mexico. News of this test was brought to the new American President, Harry Truman. Truman realized that the atomic bomb was a terrible new force for destruction. Still, after consulting with his advisers, he decides to use the new weapon against Japan. Truman warned the Japanese that if they did not surrender, they would face "a rain of ruin from the air the like of which has nerver been seen on this Earth." When the Japanese ignored the deadline, the United States took action. On August 6, 1945 an American plane dropped an atomic bomb, "little boy", on Hiroshima and killed between 80-100 thousand people. Japan still refuses to surrender, so 3 days later, August 9, another American plane dropped "Fat Man" on Nagasaki that killed between 60-75 thousand people. Then on August 14, 1945 Japan surrenders.
yes, it was during that war that the two nuclear bombs were dropped over Japan.
