Well done, congratulations, and thanks! It was a good and brisk read!
I think you did a good job of showing how marginalized (even over OTL) nazism would be ITTL post-war. One possible side effect of that would probably be more mainstream flirtation with nazi kitsch. You hear about these themed bars and restaurants in south and east Asia IOTL, places where the horror had no direct impact. Maybe that fascination with aesthetics is more widespread ITTL. Like I had a friend in high school who wore a Red Army outfit for Halloween one year, as a big joke (she was a libertarian). I shudder to think what she would’ve worn ITTL...
I’ve got some questions about the post-war settlement. Just to point out the most obvious first, I don’t think you mentioned Finland gaining as much territory as is depicted in the map. It might just be a mistake, but I can see the security arguments in favor of it. It does leave a relative lot of Russians in Finnish territory (relative to the not-very-large population of Finland).
And that leads me to another question: wholesale population removal. IOTL the Soviets got away with lots of it, before, during, and for a while after the war. They did it to Germans in Czechoslovakia and new western Polish territories with tacit acceptance by the Western Allies. ITTL one might think the practice of wholesale depopulation- basically by modern time IOTL considered a form of ethnic cleansing- might be verboten right off the bat, as a favored and particular tool of evil-doers. And yet here’s Poland and Lithuania doing it (almost certainly with allied help), possibly Finland, possibly Ukraine, possibly Japan. I get that the tactic has a certain...brute practicality to it that’s hard to ignore, and we have such justification arguments over Hiroshima and Nagasaki IOTL. Perhaps that’s the comparison I’m looking for?
Another note on territory, I think the map shows Tuva under Chinese control as well, which seems reasonable if the timing works out (i.e. they can physically walk there before the war ends). It’s not ethnically Russian even today, after all. And it looks like the map also splits off at least part of Tajikistan for the Brits. Again, could be a zealous mapmaker, but a very minor “rush ahead and put a flag on it” campaign at the end could justify it.
I’m a little surprised the Northern Caucasus didn’t rebel sufficiently in the final months of war to justify independence, considering it’s impossible to clear the various peoples from those mountains and they love to rebel and had at least a tentative history of working together briefly in the form of the Mountain Republic. Now, post-war the place would be a shit show to make the Balkans look like a trip to the seaside, but that might just have Russia counting her blessings.
Be interesting to go into decolonization as well. With no alternative power bases to turn to for support, colonies might have little choice but to keep up ties with their former masters. But something tells me what it really means is a lot more power for the US. I can also see something like Pan-Africanism being a lot stronger ITTL.
