Yeah, Curtis Le May appears to definitely be continuing his contention for the utter destruction of the Japanese people through starving them to death and burning their cities to the ground, which was his strategy during the war. I wouldn't recommend citing him as a source
against the point that we would have ended up killing a lot more Japanese
without the A-Bombs,
given that killing a lot more Japanese by not using the A-Bombs was his preferred plan.
Your own claims fit well here:
Another myth that has attained wide attention is that at least several of Truman's top military advisers later informed him that using atomic bombs against Japan would be militarily unnecessary or immoral, or both. There is no persuasive evidence that any of them did so. None of the Joint Chiefs ever made such a claim, although one inventive author has tried to make it appear that Leahy did by braiding together several unrelated passages from the admiral's memoirs. Actually, two days after Hiroshima, Truman told aides that Leahy had 'said up to the last that it wouldn't go off.'
Neither MacArthur nor Nimitz ever communicated to Truman any change of mind about the need for invasion or expressed reservations about using the bombs. When first informed about their imminent use only days before Hiroshima, MacArthur responded with a lecture on the future of atomic warfare and even after Hiroshima strongly recommended that the invasion go forward. Nimitz, from whose jurisdiction the atomic strikes would be launched, was notified in early 1945. 'This sounds fine,' he told the courier, 'but this is only February. Can't we get one sooner?'...
As do mine:
... Even after the triple shock of the Soviet intervention and two atomic bombs, the Japanese cabinet was still deadlocked, incapable of deciding upon a course of action due to the power of the Army and Navy factions in cabinet, and of their unwillingness to even consider surrender. Following the personal intervention of the emperor to break the deadlock in favour of surrender, there were no less than three separate coup attempts by senior Japanese officers to try to prevent the surrender and take the Emperor into 'protective custody'. Once these coup attempts had failed, senior leaders of the air force and Navy ordered bombing and kamikaze raids on the U.S. fleet (in which some Japanese generals personally participated) to try to derail any possibility of peace. It is clear from these accounts that while many in the civilian government knew the war could not be won, the power of the military in the Japanese government kept surrender from even being considered as a real option prior to the two atomic bombs.[73] ...
And, of course, we are able to now cite the actual text of Emperor Hirohito's surrender speech:
Moreover, the enemy has begun to employ a new and most cruel bomb, the power of which to do damage is, indeed, incalculable, taking the toll of many innocent lives. Should We continue to fight, not only would it result in an ultimate collapse and obliteration of the Japanese nation, but also it would lead to the total extinction of human civilization. Such being the case, how are We to save the millions of Our subjects, or to atone Ourselves before the hallowed spirits of Our Imperial Ancestors? This is the reason why We have ordered the acceptance of the provisions of the Joint Declaration of the Powers.
