well perhaps i should limit it to the eastern slavs, but it was always a project to colonize poland/russia. and as war progressed not in germany fafvour their racial views lost rigidity in an attempt to field more troops from occupied territories. in reality when war started many russians wanted to join 3rd reich to fight communists but when ss started executing them left and right they had no other choice than to join communists instead and fight to the death which in turn actually forged communist nation since wars are always nation-building processes if you can win them.
