"Throughout the war, the four of us- Marshall, King, Arnold, and myself- worked in the closest possible harmony. In the postwar period, General Marshall and I disagreed sharply on some aspects of our foreign political policy. However, as a soldier, he was in my opinion one of the best, and his drive, courage, and imagination transformed America's citizen army into the most magnificent fighting force ever assembled. In number of men and logistical requirements, his army operations were by far the largest. This meant that more time of the Joint Chiefs were spent on his problems than on any others- and he invariably presented them with skill and clarity. King had an equally difficult task. His fleets had to hold Japan at bay while convoying millions of tons of supplies for the second front. He was an exceptionally able sea commander. He was also explosive and there were times when it was just as well that the deliberations of the Joint Chiefs were a well-kept secret. The President had a high opinion of King's ability but he was a very undiplomatic person, especially when the Admiral's low boiling point would be reached in some altercation with the British. King would have preferred to put more power into the Asiatic war earlier. He supported loyally the general strategy of beating Germany first, but this often required concessions of ships which he did not like to make. He could not spare much, since, until the last months of the war, he was working with a deficit of ships. America was fighting a two-ocean war for the first time in its history."

“Everybody may have peace if they are willing to pay any price for it. Part of this any price is slavery, dishonor of your women, destruction of your homes, denial of your God. I have seen all of these abominations in other parts of the world paid as the price of not resisting invasion, and I have no thought that the inhabitants of this state of my birth have any desire for peace at that price, or that they lack the fortitude that is necessary to discourage aggression by the barbarians who are now about to be driven back to their kennels, or by any other savages who may arise at some later date against our civilized Christian world.”

“such a superlative quality of excellence... that there is no other individual... capable of preparing and delivering a comparable address... The public enthusiasm for General MacArthur in San Francisco and in Washington was a triumph beyond anything that I have ever seen anywhere for anybody, which seems strange in view of his recent summary detachment by President Truman. If the general's popularity persists for a considerable time, it should actively effect a change in the country's domestic political policy, and it might have a radical effect on the complexion of domestic political development. From a purely military point of view it appears that General MacArthur's attitude will be fully accepted by all qualified military authorities.”

“I did not see Julius Caesar's return to Rome, but I am sure that in comparison it looked like a deuce of spades.”

“Once it had been tested, President Truman faced the decision as to whether to use it. He did not like the idea, but was persuaded that it would shorten the war against Japan and save American lives. It is my opinion that the use of this barbarous weapon at Hiroshima and Nakasaki 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. It was my reaction that the scientists and others wanted to make this test because of the vast sums that had been spent on the project. Truman knew that, and so did the other people involved. However, the Chief Executive made a decision to use the bomb on two cities in Japan. We had produced only two bombs at that time. We did not know which cities would be the targets, but the President specified that the bombs should be used against military facilities. I realized that my original error in discounting the effectiveness of the atomic bomb was based on long experience with explosives in the Navy. I had specialized in gunnery and at one time headed the Navy Department's Bureau of Ordnance. "Bomb" is the wrong word to use for this new weapon. It is not a bomb. It is a poisonous thing that kills people by its deadly radioactive action, more than by the explosive force it develops.”

“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. We were the first to have this weapon in our possession, and the first to use it. There is a practical reality that potential enemies will have it in the future and that atomic bombs will sometime be used against us. That is why, as a professional military man with a half-century of service to his government, I come to the end of my war story with an apprehension about the future. These new concepts of "total war" are basically distasteful to the soldier and sailor of my generation. Employment of the atomic bomb in war will take us back in cruelty toward non-combatants to the days of Genghis Khan. It will be a war of pillage and rape of a society, done impersonally by one state against another, whereas in the Dark Ages it was a result of individual greed and terrorism. Thee new and terrible instruments of uncivilized warfare represent a modern type of barbarism not worthy of Christian man. One of the professors associated with the Manhattan Project told me that he had hoped the bomb wouldn't work. I wish that he had been right.”

“Perhaps there is some hope that its capacity for death and terror among the defenseless may restrain nations from using the atom bomb against each other, just as in the last war such fears made them avoid employment of the new and deadlier poison gases developed since World War I. However, I am forced to a reluctant conclusion that for the security of my own country which has been the guiding principle in my approach to all problems faced during my career, there is but one course open to us: Until the United Nations, or some world organization, can guarantee- and have the power to enforce that guarantee- that the world will be spared the terrors of atomic warfare, the United States must have more and better atomic bombs than any potential enemy.”
