See title. It seems like it'd be quite boring and economics-heavy, given the usual stuff about how the war had to happen because the German economy had been recklessly built on expansion. But it can't be considered ASB that at a certain point in the 1930s something, probably Hitler dying, could have happened that brought a consolidation-focused leader such as Goering to power, who then changed course economically and drew a line under German territorial demands after a peaceful return of the Polish corridor.
It's quite un-sexy to have the Nazis survive into the late 1940s and OTL post-war world without them killing millions of people in a horrific war in the process, but has it ever been attempted? I'd quite like to give it a read, I'm sure it's not as dry as it seems. The longer-term contradictions of the Nazi state would have been completely differently explored during peacetime, there's even the possibility that come the death of this Hitler-replacement, free elections of some description might be held.
Of course, the other possibility (and this would be a TL a lot of people would read) would be a 1942ish invasion of Eastern Europe by Stalin, with this softer Nazi state (I'm not looking for a surviving Weimar) standing shoulder to shoulder with the WAllies. But someone could maybe butterfly (thanks to the removal of Hitler and his inherent opposition to the USSR's existence) Stalin's plans for expansion into just restoring the pre-1914 borders of the Russian Empire -perhaps conceivable if a buffer Poland is arranged and guaranteed by the League of Nations.
Anyway, I've rambled a bit because it's 11pm, but I'd be interested if there's a TL that deals with a peaceful surviving Reich.
