I'm not sure, if I were at war with the whole world, the least I would think of doing is spending so many resources on making an enormous extermination network right in the middle of it, involving 12 milion people. Peacetime? Sure, but again, here you're fighting the whole world, I'd recommend expulsion of the jews somewhere to madagascar or israel, and extermination at least when you won the war.
I guess hitler was just crazy like that? This feels more retarded than anything.
Regardless, what's more pressing is not that the holocaust didn't happen, or had less than the official 6 milion killed, but the whole industry it creates.
Every year has an official holocaust movie that gives the author a few multikulti points, other than raking large sums of cash, the holocaust industry gives jews enormous leverage, develops a victim complex etc.
I can talk about how the water is blue for as long as possible, but the deal is: the shoah is not the most killing humanity could do, many other leaders did even worse stuff, yet we don't have 5th generation genghis khan survivors talking about how terrible it was (and it certainly was!), schools don't do visits to katyn, you won't see steven spielberg direct a movie on the circassian genocide.
The holocaust is singled out because of its convenience to the narrative, you like white people thus you like hitler, hitler did the holocaust, so you want to put all non-whites in ovens.
