J. Robert Oppenheimer with General Leslie Groves at Trinity Site, July 1945.
"If there were to be a decision on whether to use the bomb, that decision would be made - theoretically, at least - not by Leo Szilard and the disaffected Chicago scientists but by the nation's leaders. Yet during the long spring of 1945, few of the men at the top seemed willing to even talk..."
The General and the Bomb
"President Truman knew of these diverse and conflicting opinions. He must have engaged in some real soul-searching before reaching his final decision."

DWIGHT EISENHOWER
"...in [July] 1945... Secretary of War Stimson, visiting my headquarters in Germany, informed me that our government was preparing to drop an atomic bomb on Japan. I was one of those who felt that there were a number of cogent reasons to question the wisdom of such an act. ...the Secretary, upon giving me the news of the successful bomb test in New Mexico, and of the plan for using it, asked for my reaction, apparently expecting a vigorous assent.
"During his recitation of the relevant facts, I had been conscious of a feeling of depression and so I voiced to him my grave misgivings, first on the basis of my belief that Japan was already defeated and that dropping the bomb was completely unnecessary, and secondly because I thought that our country should avoid shocking world opinion by the use of a weapon whose employment was, I thought, no longer mandatory as a measure to save American lives. It was my belief that Japan was, at that very moment, seeking some way to surrender with a minimum loss of 'face'. The Secretary was deeply perturbed by my attitude..."

In a Newsweek interview, Eisenhower again recalled the meeting with Stimson:
"...the Japanese were ready to surrender and it wasn't necessary to hit them with that awful thing."

ADMIRAL WILLIAM D. LEAHY
(Chief of Staff to Presidents Franklin Roosevelt and Harry Truman)
"It is my opinion that the use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender because of the effective sea blockade and the successful bombing with conventional weapons."The lethal possibilities of atomic warfare in the future are frightening. My own feeling was that in being the first to use it, we had adopted an ethical standard common to the barbarians of the Dark Ages. I was not taught to make war in that fashion, and wars cannot be won by destroying women and children."
