Hitler lost the war as soon as he declared against Russia. Had he left them alone then he could concievably have held on to his European conquests, instead of spreading his forces out over several fronts. The decision to break the neutrality treaty was extremely stupid and is enough of a bonehead manuever to exclude Hitler as being good enough to be considered for Civ. Except maybe in some special scenario. But that will never happen due to his bad rep in today's world.
