I have had the "privilege" of reading Mein Kampf from cover to cover when I was younger. (better then Ayn Rand, but both pale in comparison to Stephen Kings "It" in sucky long wordiness.
Hitler was damn ballsy to lay it ALL out in that book while he was in jail. Very interesting to read and know your WW2 history after the fact. He followed his plan almost to the letter. And only a few paid attention.
Granted WW2 kinda spoils the end of Mein Kampf since we all know the 1000 year reich gets its ass kicked. (well all of us except Ann Coulter or Spidey maybe)
Anywaaaay...
Hitler framed the whole deal as a religious christian teutonic crusade. Gods chosen: the "ubermenchen".
In case your German is rusty that's "God With Us."
Most Wehrmacht soldiers were issued this as belt buckles. -From Hitlers personal orders mind you.
Look at just about any genocide in history, you are damn hard pressed to find religion not creeping its way into it or the outright justification.
