Instead of WW2, the Germans should have just sent hordes of needy German families into Czechoslovakia, then Poland, Denmark, Norway, France.....
Barbarossa should have been caravans of German migrants making their way to Stalingrad for a better life. A much cheaper and effective battle plan.
This is an invasion of Europe that is even worse than WW2. After WW2, France still was for the French, Germany-Germans, etc... Now, gradually, without tanks or aircraft, you will become minorities in your own countries and there's not a damn thing you will do about it....because someone will call you a bad word.
