The Russian people suffered horribly under ninety years of evil communism. Yet will always wonder how many current Americans would have not come to exist if the Russians, who suffered horrendous casualties, had not fought the Germans so well and had not destroyed the best of the German war machine. If America had to attack Europe against a relatively intact German army,wonder how many of our grandfathers and fathers would have never returned to procreate.
Of course another question would have been, what if everyone just stayed out of it and let the Nazis and Bolsheviks bash each others brains in?
