Well I mean like I said in another post, I know what Hitler's tendencies are. I thought the whole point of this thread was to formulate a theory by which Hitler would actually succeed with his goals. This would have to include befriending SOME Slavs, like Baltic Slavs and Ukrainians. It's doable, but Hitler's persona would have to be radically altered, with strict military attention cast against Bolshevism as an ideology, not Slavs as an ethnic group.
Then I'll repeat my first point:
You want him to not be Hitler.
The argument you are advancing is "if Hitler didn't act like Hitler he could have won." Which is false, because without the drive, and the insanity behind it Hitler isn't going to end up in charge of Germany. Extermination of the populace of the East wasn't some side project, it was the central tenet of Nazism.
Once you've stripped that away, they aren't Nazis anymore.
I should note, this is also why I HATE media where the villains are compared to Nazis. Hydra for example is supposed to be the ultimate evil force, a group so bad even the Nazis didn't agree with them...
Problem is, Hydra has basically never done anything the Nazis ACTUALLY did. The Captain America movie where the evil scheme is to nuke 15 cities? Ha.
The Nazis were planning to exterminate over 90 million people, bulldoze their cities, and pretend the civilization never existed. They killed 12 million people in concentration camps WHILE LOSING. Not to mention millions more through sheer brutality in the East.
These things are inherent to Nazism.
