In fact, there is a deeper connection between the Nazi movement and the Islamic State, an association that I noted some time ago. George Orwell, in his review of Mein Kampf in 1940, descried the essence of the problem:
Hitler knows… that human beings don’t only want comfort, safety, short working-hours, hygiene … and, in general, common sense; they also, at least intermittently, want struggle and self-sacrifice… Whereas Socialism, and even capitalism in a more grudging way, have said to people ‘I offer you a good time,’ Hitler has said to them ‘I offer you struggle, danger and death,’ and as a result a whole nation flings itself at his feet.
