I liken Hitler (and Stalin to great extent, with the Italian dictator thrown in) to something found in Daniel, Old Testament, where Daniel has been praying earnestly for an answer from God, for weeks, when suddenly an entity appears to Daniel by the River Chabar, to answer his prayers. The Angel explains that it has been restrained from coming to Damiel because of a demonic power working Persia. There appears to have been a demonic power working the developed nations, along the lines of this racial purity notion twisted to support all manner of evil.
