The core problem involves the Koran’s teaching that Mohammed represents the last prophet, that his revelations amount to the ultimate “seal of knowledge,” and that a just, well-ordered world will place his faithful followers in positions of greater power, prosperity and peacefulness than their infidel neighbors. For anyone who takes Islamic teaching seriously, the current state of the world offers a glaring, painful example of cognitive dissonance: the backwardness, poverty, and endemic misery of Muslim societies—particularly compared to the privilege and prosperity of the West—either undermines the validity of the Holy Koran, or proves that evil infidel conspirators have upset the natural, proper, and Godly order of things. In the 1930’s, the passion behind Nazism arose from a burning sense that the German people had been gypped, that the infamous “stab in the back” of the Versailles Treaty had deprived the nation of its rightful position of world leadership. Islamo-Nazis feel an even more galling sense of injustice, oppression and unfairness, since hostile forces have, in the view of the devout, denied them the chance to live out their divine endowment of world dominance.
