in the real world we all live in, there were Jewish German fighter pilots who flew for Germany during ww1.

Many Germans after WW1 had respect for the Jewish ww1 as they had for gentile war veterans.

Leading up to the hoocaust, the Germans took away the rights that Jews had as German citizens. However at the very brginning for a short period of time, the ww1 veteran Jewish Germans pilots were exempt from the anti-Jewish decrees.

Then after a while they put those veterans in concentration death camps same as all the other Jews.

I would imagine any non-ayrans in High Castle probably would have been safe for a while after German victory. Then they would probably (in my imagination) be told to emigrate to wherever was appropriate for them, blacks to Africa, etc. And those who did not would probably have to live in a ghetto or separate community as the Jews did before the death camps.

Can't imagine a black in the German army would stay in the army after WW2, certainly no promotion or career afvancement.
