The Nazis had the Slavs in their crosshairs, even if they were blue eyed blonds with nearly 100% Swedish background.
I really don't think anything the Germans did in WWII is defensible ~ NOT ONE THING.
The people who lived in that part of the world will judge the merits of Nazism and Bolshevism; the first half of the 20th century indicates they preferred the former, usually as a defense against the latter.
The example of the Ukrainian women is great; how many Ukrainians DIED as unpaid slave laborers in the 1930s and 1950s? There was a reason why they preferred Hitler to Stalin; they knew Stalin wasn’t the cuddly “Uncle Joe” our lying government sold to us, and they didn’t yet know just how bad Hitler really was.
If WWII was really between the Nazis and the Bolsheviks, the US had no reason to fight in it. If Japan attacked us, we could destroy them while avoiding Europe (as Stalin did, fighting in Europe while avoiding the Far East). There was no reason to choose sides when Satan battled Lucifer; the only losers were the people in that part of the world.
The Nazis stole blonde-haired Polish kids and Germanized them and gave them to German families. Hitler planned to eliminate the Polish race by 1975, through sterilization.
