Just randomly they did.
Japan refused to surrender after the first atomic bomb.
When the atomic bomb was finished, Leo Szilard, a scientist in on the Manhattan Project (the Manhattan Project was the code name for the project to build and develop the atomic bomb), made a petition urging the President not to resort the use of atomic bombs in the war unless the news of the bomb had been made open in public and on terms that Japan knows and refuses to surrender. The petition was signed by over 150 scientists in on the project. A counterpetition garners only two signatures. Japan, of course, refused to surrender. The result was the flattening of two major cities in Japan.
The little boy bomb was droped on Japan, then one more bomb was droped Japan indangering all of Japan, so the comander signed a peace treaty.
