Of course, the concentration camps would have continued to operate. England would have has some Nazi puppet king, probably. Big business would have ended up adjusting to the new order and would have done just fine. Except for one little thing. It is quite possible that the Communist Evil would have been kept at bay by the National Socialist Evil. One little problem with all this worldy view, though.
Evil would have had a great Victory. To stand there and tolerate evil to flourish because it might all turn out better for us in the long run if we do nothing, is wrong. The worldly Frenchamn doesn't give a damn about evil, though. As long as gets his 35-hour work week, excellent vactaion benefits, and at least two good French meals each day, he couldn't care less about right and wrong. Heck it sounds pretty attractive me right now (when compared to dying on a Becah in Normandy), but it is wrong.
So the Germans can march in the shade.
An old joke I heard while in the Army.
