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?'

The best that can be said about Eisenhower's memory is that it had become flawed by the passage of time.

Notes made by one of Stimson's aides indicate that there was a discussion of atomic bombs, but there is no mention of any protest on Eisenhower's part.[74]

Even after both bombs had fallen and Russia entered the war, Japanese militants insisted on such lenient peace terms that moderates knew there was no sense even transmitting them to the United States. Hirohito had to intervene personally on two occasions during the next few days to induce hardliners to abandon their conditions. That they would have conceded defeat months earlier, before such calamities struck, is far-fetched to say the least.

The Strategic Bombing Survey outright ignored material that didn't fit their conclusion on the Pacific War, and I am aware of no serious trend in modern historical academia that regards the atomic bombings and the Soviet invasion and the impending American invasion to be immaterial in Japan's surrender.

First, I trust the numerous first hand accounts of actual leaders of the time over this one historian acting like their memories aren't great fifty years after the fact.

Second, the imminent Soviet invasion absolutely was a material factor. One of the reasons why the nukes were used were to end the war before the Soviets could invade so they couldn't dictate any terms of surrender.

This may be shocking, but leaders often lie. Only Eisenhower's memory was impugned in that statement. Sorry that contemporary accounts don't back up their later politiking.

Second, the imminent Soviet invasion absolutely was a material factor.

Then why the fuck did you quote

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. - US Government Strategic Bombing Survey, 1946

Ah. I checked your comment history. A campist bootlicker. I think we're done here.

A material factor in the decision for the bombs to be dropped, not in the necessity for Japan to surrender. Those are two different things.

That historian is actually citing Japanese sources, which is more accurate than what the US leaders may have thought to be the case.

Hirohito actually used both the bombs as well as the Soviet invasion as justification to surrender. The civilian population was told it was due to the destructive power of the atomic bomb, the military were told they could not hold out against the Soviets.

It's not unlikely that not dropping the bombs would have led to a Japanese surrender, but it would likely have delayed it by some time. The bombs contributed greatly to the emergency meetings of the Japanese war cabinet in which ultimately the emperor decided to surrender. But it was a multitude of factors; the emperor was for example also unconvinced that the defense of southern Japan would be ready in time for the invasion, as earlier timelines hadn't been met. But he also said he did not want Japan and its innocent civilians destroyed due to further atomic bombs.
