Completion of the A-Bomb 

Home After the completion of the atomic bomb, Truman had a hard time deciding whether or not to use it on the Japanese to make them surrender. He had little time to decide whether to use the bombs on Japan because only Leahy, an admiral in the war, Byrnes, Secretary of State at the time of the war, and Groves, a general in the war, told him about the a-bomb and gave him some idea of the destructive capability they had. Shortly after he became president, some of the bombs were ready to be used. Because of this, he had tests issued to ensure that the U.S. didn’t underestimate its power and use it wrongly. These tests took place in desert areas, like Alamogordo, New Mexico.
