James Woolsey warns us not to underestimate the power of the Salafist vision:

...the Salafists' theocratic totalitarian dream has some features in common with the secular totalitarian dreams of the twentieth century, e.g., the Nazis' Thousand Year Reich, or the Communists' World Communism. The latter two movements produced tens of millions of deaths in the 20th century in part because, at least in their early stages, they engendered "fire in the minds of men" in Germany, Russia, and China and were able to establish national bases. Salafists had such a national base for the better part of a decade in Afghanistan and have had one controlling the Arabian Peninsula for some eight decades. They haven't attained the Nazis' and Communists' death totals yet, but this is only due to lack of power, not to less murderous or less totalitarian objectives...(The president's "Islamofascist" term is thus perhaps understated — the Italian fascists were horrible, but not genocidal. "IslamoNazi" would be more accurate.)

Take note, Mr. Simon.
