So let me get this straight. When we point out a single factor in something, and don't point out the other ones because others have already made them obvious, we are somehow saying that that single factor is actually the only factor?
I don't have to acknowledge any other basis for it. Saying "X relies upon Y" has never been understood to mean that "X relies solely upon Y".
And I called you complicit in the ideological narrative because you are, and seem to be incapable of admitting "Gosh, people sixty plus years ago were racist".
The racial attitudes of that period are well documented, and they permeated all levels of society. Our own propaganda relied upon it. I don't think the propaganda makers and the policy makers were some how immune to this social phenomenon that was a whole hell of a lot older than they were.
I am quite willing to acknowledge people sixty years ago were racist. They segregated blood banks, for crying out loud, and interned 300,000 Japanese-Americans on the mainland, where the population had engaged in no shenanigans whatsoever, while leaving the J-A population of the Hawaiian Islands (which included spies for Japan and a small number who actively helped a downed Japanese pilot after Pearl Harbor) alone because they were too economically useful.
However, you jumped in with both feet on the racism angle without much supporting evidence and a lot of belligerence, without even a scintilla of anything about "sloppy analysis" that you brought in later. And then when I had the gall to disagree with you, you went straight to accusations of moral cowardice.
Furthermore, even if the A-Bomb was unnecessary, did the American war planners know that Downfall wasn't going to be Iwo Jima or Okinawa 2.0? They didn't need to believe anything about Mindless Asian Hordes to think that the Japanese would fight even more fiercely in defense of their Home Islands than a couple of colonial possessions.
In fact, given the importance of these possessions to the defense of their Home Islands, that would explain why they fought for them so hard. Logically, they would fight even harder for their actual homes.
Look at Germany. They were fighting well past the "quit while you're ahead" point. Why should the Japanese be any different?
And lecturing me about an ideological narrative is rich consider you identify yourself as a Marxist in your personal profile. Marxism is a much more specific ideological entity than "capitalism" or "Americanism."
