Washington’s Blog: Like all Americans, I was taught that the U.S. dropped nuclear bombs on Hiroshima and Nagasaki in order to end WWII and save both American and Japanese lives.
But most of the top American military officials at the time said otherwise.
The U.S. Strategic Bombing Survey group, assigned by President Truman to study the air attacks on Japan, produced a report in July of 1946 that concluded (52-56):
Based on a detailed investigation of all the facts and supported by the testimony of the surviving Japanese leaders involved, it is the Survey’s opinion that certainly prior to 31 December 1945 and in all probability prior to 1 November 1945, Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated.
General (and later president) Dwight Eisenhower – then Supreme Commander of all Allied Forces, and the officer who created most of America’s WWII military plans for Europe and Japan – said:
The Japanese were ready to surrender and it wasn’t necessary to hit them with that awful thing.

Eisenhower also noted (pg. 380):
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….
Admiral William Leahy – the highest ranking member of the U.S. military from 1942 until retiring in 1949, who was the first de facto Chairman of the Joint Chiefs of Staff, and who was at the center of all major American military decisions in World War II – wrote (pg. 441):
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.
