Mohammed and Joseph Smith were much smarter than Hitler, they dressed up their cults as “religions” that became self-sustaining.
Hitler’s cat’s-paw Himmler dabbled in Odin-worship & praising the Nordic gods of Wagnerian legend, and even tried to establish a “National Reich Church”.
But except for a handful of hardcore SS-Totenkopf & their `temple’ at Schloss Wewelsburg, the notion of a Nazi “religion” was a joke to Germans.
Hitler was an atheist. How do you create something from nothingness?
