The Decision to Drop the Atomic Bomb On December 7, 1941, Japan bombed the United States naval facility known as Pearl Harbor. This attack brought the United States into World War Two. Within the four years that followed, the United States--under the presidency of Franklin D. Roosevelt-- researched and developed an atomic bomb. This was known as the Manhattan Project. Such a bomb was more powerful and destructive than any ever known to man.

President Truman decided to use the atomic bomb when things were getting worse. The decision to use the atomic bomb was a difficult one and many people wonder if it was the right choice. When the United States caught word that Germany was close to creating the atomic bomb, J. Robert Oppenheimer and other scientists wanted to create it first, for the U.S. After three years of research, the first small atomic device was exploded on July 16, 1945 in the lab at Los Alamos. Having proved their concept worked, a larger scale bomb was built. Less than a month later, atomic bombs were dropped on Hiroshima and Nagasaki in Japan (Rosenberg).
