Since you consider 1,000,000 American casualties "a load of hogwash", would you consider several million Japanese casualties hogwash?
It is a fact that fewer Japanese died as a result of the bombs than would have died in an invasion of the main land.
Not that I disagree with anything you said, but there is a factual disconnect that is used to forward the 'it wasn't necessary' argument that is important to grasping the argument: The Japanese were looking to start negotiating a surrender prior to the dropping of the bomb. Simple conclusion: the US could have accepted a surrender without dropping the bomb or invading Japan.
As I worded that, the first sentence is factually accurate and the second a reasonable conclusion. But that argument vague and misleading to the point of being being an intentional obfuscation. The internet is littered with such arguments. I found one that quoted a couple of prominent generals/admirals saying the Japanese could no longer mount an effective fight and that the war was basically won, then twisted that into Truman getting unanamous advice that it wasn't necessary. That's just not factually accurate and more importantly, Truman was
correct that there was a camp in Japan favoring fighting to the death rather than surrendering at all:
Faced with the prospect of an invasion of the Home Islands starting with Kyūshū, and also the prospect of a Soviet invasion of Manchuria, Japan's last source of natural resources, the War Journal of the Imperial Headquarters concluded:
We can no longer direct the war with any hope of success. The only course left is for Japan's one hundred million people to sacrifice their lives by charging the enemy to make them lose the will to fight.[9]

So what we know for fact:
1. The Americans knew Japan could no longer win.
2. The Japanese knew Japan could no longer win.
3. The Japanese put out feelers for negotiating surrender conditions but never stated explicitly what conditions they were willing to accept.
4. Some Japanese leadership advocated fighting to the death -- including the entire civilian population.
5. Japanese fighters had a history of fighting to the death.
6. The nuclear bomb attacks were spectacular, but were not the worst bombing raids of the war. The worst was the March 9-10 "firebombing" of Tokyo. With that in mind, those two nuclear bombs were tough to consider much different than just an unusually efficient conventional bomb.
Given all these facts, it is difficult to see Truman's decision as being "wrong" insofar as whether it was logical or illogical. Moral? That's a matter of opinion and in since in war there are a lot of immoral acts, that seems a difficult and potentially unreasonable question depending on the criteria.
Bringing us back to the topic of the thread: I consider making the "right" decision despite extreme difficulty or distastefulness of the decision to be a hallmark of good leadership, so I consider that decision to be a sign that Truman was a great President.
