The high end of the range of death estimates by the two atomic bombs is around 246,000. The estimated range of US military deaths from an invasion of Japan (Operation Downfall) was 250,000 to 1,000,000, and another 5 to 10 million Japanese. Dropping nukes was both barbaric and the more civilized option. Oppenheimer et al. deserve their acclaim.
Japan attacked the US first, and by Hiroshima the US had 110,000 dead in the Pacific theater. Imagine living through that before judging them.

Also perhaps worth noting that after the first bomb the Japanese government was not planning to surrender. The second dropping moved things to a deadlock where half of the ministers—both in the small war council, and the larger full government—wanted to the surrender and the other half did not.
The Emperor had to be called in—an almost unprecedented action—to break the tie. Then, even after the Emperor had made his decision, there was a coup attempt to prevent the "surrender"† broadcast:

I do not know how anyone can think that Japan would have stopped fighting without the bombings when two bombings barely got things over the line.
The book 140 days to Hiroshima by David Dean Barrett goes over the meeting minutes / deliberations and interviews to outline the timeline, and it was not a sure thing that the surrender was going to happen: the hardliners really wanted to keep fighting, and they were ready to go to great lengths to get their way (see Kyūjō above).
The Japanese knew for a year before the bombings that they could not win the war, but they figured that by holding out—causing more causalities of Japanese, Americans, Chinese, Filipinos, etc—the US would lose their resolve and terms could be negotiated so that Japan could (e.g.) keep the land they conquered in Manchuria, etc.
† A word not actually used by the Japanese in the broadcast.
The US had already secretly intercepted cables from Japan with it looking to "terminate the war because of the pressing situation which confronts Japan" as far back as July 12th 1945 in which they also expressed a willingness to relinquish all claimed territories. [1] The only condition they were seeking is that the Emperor be able to remain as a figurehead.
That urgency and willingness to surrender was before Japan knew that the USSR had already agreed with the allies to declare war on them at the Yalta conference in February. The USSR committed to declaring war on Japan "two or three" months after Germany fell, which happened on May 8th. They declared war on Japan on August 8th.
We did not forward any of this information onto the other allies. Instead we chose to nuke Japan on August 6th. The Emperor was allowed to remain as a figurehead.

Pro tip: if your enemy is really about to surrender, nuking them once will suffice. Even after the second bomb was dropped, the Emperor faced assassination threats from the military high command for running up the white flag.
More to the point, while Hiroshima and Nagasaki were horrible events, they were cheap lessons compared to what it would have cost humanity to establish the taboo of nuclear warfare later, in Korea or elsewhere, with bombs 10x to 1000x their size.
Like you're indirectly acknowledging, the nukes had no real impact on their decision. Half their way cabinet wanted to fight to the last Japanese, half wanted to surrender. This was both before and after the nukes. The Emperor wasn't like a super-politician - he was seen as a [literally] living deity who was above politics. So the cabinet called upon him to make the final decision, which he had made long before the nukes - which was to surrender. There was no danger to him. Even the plots to undermine his decision involved destroying his announcement of surrender and leaving him under house arrest. And that plot was stopped by a speech from another officer, leading to most of the plotters to commit suicide for their dishonor.
And I don't think there were any real lessons learned. We nearly nuked ourselves during the Cold War multiple times. And today, with bombs that make Hiroshima and Nagasaki look like primitive weapons, you have people acting like nuclear war isn't something 'that' fearful. We killed hundreds of thousands of people largely for the sake of trying to get a slight geopolitical edge over the USSR. And that's far better than the alternative of there being no reason at all. In no world are the arguments about it saving lives valid, even if you attach 0 value to the life of the Japanese for having audacity to be born in the wrong country.

Leo Szilard was a critical scientist in the story of the atomic bomb, and he's also full of just amazingly insightful quotes. [1]
- Suppose Germany had developed two bombs before we had any bombs. And suppose Germany had dropped one bomb, say, on Rochester and the other on Buffalo, and then having run out of bombs she would have lost the war. Can anyone doubt that we would then have defined the dropping of atomic bombs on cities as a war crime, and that we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them?
- A great power imposes the obligation of exercising restraint, and we did not live up to this obligation. I think this affected many of the scientists in a subtle sense, and it diminished their desire to continue to work on the bomb.
- Even in times of war, you can see current events in their historical perspective, provided that your passion for the truth prevails over your bias in favor of your own nation.

The reason nuclear bombs are "uncivilized" isn't directly related to the number of deaths due to use of a single one. The reason is that the by using nuclear bombs, the US created the precedent for the usage of the only weapon humans have created that, if used by all sides, can result in effectively billions dead at extremely low cost.
To kill a billion people by conventional bombs would require years of sustained effort costing trillions of dollars, and I imagine the army doing that killing would collapse under the moral horror of its own actions far before that number is reached. On that other hand, thousands of nuclear weapons can be deployed by a very small group of amoral people with instantaneous destructive effects.
> The estimated range of US military deaths from an invasion of Japan (Operation Downfall) was 250,000 to 1,000,000, and another 5 to 10 million Japanese.
I've read convincing arguments (sorry, I cannot find them now) that this reasoning is mostly bogus.
One, the decision of dropping the bombs wasn't coordinated with planners of Operation Downfall, so casualties weren't a consideration. As such, it cannot be "civilized" (because the intent to be civilized just wasn't there).
Two, those casualty numbers rest on arbitrary assumptions about what the Japanese would or wouldn't do that don't hold up to real scrutiny, and ignore a host of options other than "full scale invasion" or "nuke".
Three, you cannot discount the flex towards the USSR, an argument many Japanese to this day maintain was a major reason. Which wasn't a civilized reason either.
On the other hand, it doesn’t matter how off the estimates were because they’re our people and their lives matter more.
It seems rather immoral to a high degree to send some Americans to their deaths unnecessarily because we didn’t want to use a weapon we had in our possession to end a war that we did not start.
The history on this is pretty sound ... a major bombing campaign was started much earlier to avoid any invasion or boots on the ground.
Seventy two Japanese cities, including Tokyo, were already completely destroyed before the two atomic bombs were dropped. The two cities destroyed by atomic bombs were on a list to be destroyed regardless.
To the people killed, injured, or left in the shell of a city with no food or water it made very little real difference whether the cause was HE+incendiaries OR high burst shockwave from atomic bomb - the M&M statistics (death and injury, both immediate and following) were similar in either case.
The greatest military imperative to drop the atomic bombs were pragmatic .. they were developed at vast expanse for use on Germany but were not ready until after Germany surrended .. to close off an R&D program without a live target test on targets already targetted for destruction just seemed ... wasteful.
After the bombs were dropped, everything changed. Public awareness and perception. The need for post war PR. The start of the Cold War race with soviets over atomics. The pressing need for auto biographies and centre staging from actors late to the story, etc.
Much of the "justification" for dropping atomic bombs was retconned after the fact.

"Our" people?
That kind of moral calculus simply doesn't track with me: I'm neither from the US nor Japan, plus I think considerations of "civilization" fly out the window once you start thinking like this.
But also, it's a kind of goalpost shifting. Either the calculations were the justification, in which case it matters whether they were right, or they weren't. It's not right to argue "well, the actual numbers don't matter because...".

It wasn't the a civilised option. Japan would have lost and surrendered with or without nukes. The USA nuked two cities just to demonstrate their nuclear capabilities to the Soviets.
One wonders if Stalin would have stuck to his agreement and turned back from Manchuria if we hadn't given them that little demo.
