I'm of the personal opinion that total victory of a non-fascist Europe over the Soviet Union in the theme of Germany IRL isn't possible without a massive shift in national policy. Not because they lack the strength, but because a total occupation and dismantling isn't necessary to achieve their goals and wouldn’t be worth it. As you said, they just need to carve out the richest regions in the West and maybe weaken it in the East, and the remaining Russia is basically Canada--big on paper, but demographically and resource-wise badly weakened.
This. In the end, Germany and Europe at large aren't undertaking a nation building project in Russia akin to what the US attempted in Iraq and Afghanistan. They're just seeking security. Splitting off minorities from the Russian core delivers that, especially when you're cutting off the Donbass and Caucasus from Russia with that. With a bit of luck, you'll see a Kamlyk state because of it
One of the big problems w/ German tank doctrine in the runup to WW2 was that they assumed that tanks wouldn't fight other tanks - which is why the IIIs were initially so undergunned and they developed heavy tanks (the Tiger) really late compared to the other powers. They need something to shock them out of that complacency.
Which, honestly, is kinda a fair assumption. Tanks are inherently offensive weapons. Mobility is a part of their arsenal. Defence is always more of a static job, so for anti-tank combat you have specific anti-tank guns in that
The problem with that is that Germany will face the same problems other invaders faced when they invaded Russia: Soviets can trade territory and casualties for time which they can use to counter attack and even in OTL with how desperate things were getting during the height of the German invasion, the Soviets were able to use that strategy to great effect in places like Stalingrad for instance. That's not even mentioning things like the lack of a Germany navy in either Baltic or Black seas that ensure certain places like Leningrad and Sevastopol can be supplied via the sea.
Plus with continued Soviet industralization as well as the possibility of them moving their industry to the Urals in a worst case scenario, the Soviets can and will be able to supply themselves, maybe not as good as with Land Lease but as long as they're not doing any Operation Bagration type of attacks, they can use it to slowly push the invaders back.
Yeah, but Germany isn't going to be under blockade in this scenario either. They have access to the resources of the outside world and aren't on that "we have to invade in the summer of 1941 otherwise we will simply have no oil left" timetable. Not only that, but the nature of Germany's dealings with other countries means that Molotov-Ribbentrop isn't happening and that a deal with Poland is quite likely, meaning that the German army is already starting at the doorstep of Minsk.
I'd counter-counter by noting how, by 1939, the majority of European countries had become far less democratic, though admittedly the circumstances did precipitate that. I do agree that there would be an eventual trend in a more democratic direction, and I am not saying that there isn't, but that it won't be enough (at least by the 1980's or so) to really be a complete 180 from what Lettow-Vorbeck leaves behind. I also feel that the way the democracy is presented plays a big part. Citing the American example, Americans are very proud of their democracy, whereas people from less "winner takes all" systems do not see the American system as very democratic at all. I am planning for Germany having a system somewhat akin to the First Past the Post system, but a bit more tailoured to German interests, where it is harder to shake up the system without an overwhelming opposition.
But I do completely see your point and you might be right, but I ask you to wait until we get a bit farther to decide, since the Republic is still... well, not thriving, but surviving
The difference is also that America is very much a place defined by a system of government. The US wouldn't be the US without its constitution. Europe, throughout its history, has proven that is willing to be much more flexible in how it organizes government. For the US, representative government is holy, for Europe it isn't.
In OTL the Germans reached the gates of Moscow and the Volga, but even so the Soviets managed to counterattack and slowly but surely push the Germans to the Elbe River! So, there is already a precedent in which the Soviets could simply crush the German invaders due to their demographic and industrial superiority (not to mention that having a regime with absolute control over all aspects of society makes surrender difficult). The Germans face the same threat that the German Empire feared, a Russia whose industrial power surpassed Germany's. Unfortunately for Germany, they certainly do not have the Kaiser's army, which was arguably the most powerful in the world, nor the robust economy benefiting from more than 40 years of peace and steady growth.
The German (European)-Soviet War that is coming up is going to be a very, very different beast than the Eastern Front of WW2. It's not a genocidal force moving east, and already it has been established it is willing to set up contacts with seperatists movements. They've already done that with the Ukrainians! But the Soviet offensive ability was also very dependent on lend lease. Logistics don't run themselves, and all those American made trucks make you very independent from the railroad system. Not only that, but the USSR recieved massive amounts of food aid. If the Soviet offensive ability is going to be reduced, and Germany's economy and army are going to be more durable instead of geared for the do or die offensives it was forced to preform IRL, not to forget the less existential threat Germany is to the people's of the Soviet Union, the USSR's victory is nowhere near certain. The best thing that may happen for them is conflict during the war between Germany and the lesser nationalities on the one side and Poland on the other. That's the big spanner in the works for that side of the conflict IMO
But you are falling into the trap of assuming that all the brutality was down to the Nazis being evil, whereas if you set aside the Einsatzgruppen a lot of it was committed by the ordinary soldiers of the Wehrmacht. If Germany is going into the USSR its going to be a war of conquest and the Army is going to wind up doing a lot of looting just to keep going and even non-Nazis had a great deal of content for the Slavic peoples, Hitler worked with ideas that were already there, he didn't invent them. If you want a stable, successful, powerful Germany, then the last thing you want is military adventures in the USSR, unless of course you can count on the British Empire and the USA as Allies.
No doubt that the war is going to be brutal either way. But there is a difference between a Nazi Germany that has been established for 8 years, a NSDAP that has been politically relevant for longer and a Wehrmacht running high on its own supply IRL and a much more reserved and "considerate" (don't know how to exactly put this) regime in Berlin that keeps public opinion in especially Britain in mind.
The most serious crimes of the Wehrmacht was the Hunger Plan and the calculated murder of millions of Soviet POWs, not the occasionally overzealous troops committing rape and pillage. Its frankly odd that people think that Germany, or any power is going to conquer the USSR without massive bloodshed and brutality. There is no magic cure for the logistical issues of the Germany army in Russia and the notion that they would be 'better' without all those horrible Nazis really is just buying into the clean Wehrmacht myth.
The Hunger Plan was specifically a part of the Nazi plans for the East. A Germany not set on creating its living space in the East like the Nazi's set out to isn't going to implement it. That doesn't mean I deny that the Wehrmacht didn't do its dirty deeds as a part of that IRL. But the Wehrmacht was just as much brought into line either willingly or unwillingly with the party line by that point.
A war with the USSR will see Germany still set out to create it's "living space", but its imperializing in Eastern Europe will be moreso in establishing a dependent market than killing the lot and settling German farmers there.
Which OTL one? The one that had serious organizational and qualitative problems in Poland that weren't completely fixed before Case Yellow? The one that had to fill out the ranks of the Panzer Divisions with Czech tanks? Also the idea that North Africa or Yugoslavia had an impact on the timing or outcome of Barbarossa is mythology. The Germans couldn't have provided the logistics for a larger army force and the ground conditions in Russia weren't right much before OTL Barbarossa. Basically the OTL invasion of the USSR was given a massive head start courtesy of Stalin's refusal to accept an invasion was coming and it was still doomed because they had grossly underestimated the size of the Red Army and its ability to stand up new divisions.
Honestly, this Germany is going to have a better quality army IMO because its not expanding beyond its means to meet a war deadline because of autarkic economic policy. Germany's military growth is going to be in a more sustainable manner. Ofcourse it will be smaller because of this. It may still have organisational problems, I can't really comment on that part, but it won't need to plunder the Skoda works to fill out the ranks
