Wouldnt having blacks in there forces go against all there political ideas?? If they did allow it the black soldiers would basicly be fighting for there own distruction rather they new it or not.
Well, thats a muddy issue really, technically, the Nazi's where not offended by the existance of other races, aslong as races where never mixed, so on the books, its was ok that there where black people and asian people, aslong as they stayed in their own countries (and didn't have any offending political or relegious views the nazi's didn't like, or, you know, just plain got in their way), but Jews and Gypsies where ofcourse the scum of the earth and had to be destroyed.
So technically, Nazism can also be practiced by black, asian, arab people, whatever.
But in reallity, had Nazi Germany won the war, would they really have been contempt letting "others" have precious "Lebensraum"? or would they have gone for total world domination for the "Aryan master race" some time down the line? i'd think the latter.. they where just generally douchebags like that.
