While the use of atomic weapons were not specifically mentioned in the previous versions of the Geneva conventions, the use of indiscriminate weapons against civilian target were definitively considered war crimes.
A number of notable individuals and organizations have criticized the bombings, many of them characterizing them as war crimes, crimes against humanity, and/or state terrorism. Early critics of the bombings were Albert Einstein, Eugene Wigner and Leo Szilard, who had together spurred the first bomb research in 1939 with a jointly written letter to President Roosevelt. Szilard, who had gone on to play a major role in the Manhattan Project, argued:
"Let me say only this much to the moral issue involved: Suppose Germany had developed two bombs before we had any bombs. And suppose Germany had dropped one bomb, say, on Rochester and the other on Buffalo, and then having run out of bombs she would have lost the war. Can anyone doubt that we would then have defined the dropping of atomic bombs on cities as a war crime, and that we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them?"[67]-^ "Leo Szilard, Interview: President Truman Did Not Understand.".
