ISIS draws on, and draws strength from, ideas that have broad resonance among Muslim-majority populations.

There is a strain of christian conservative in the West that tends to describe the inevitable end result of the reformation as amounting to widespread abandonment of the faith itself. Frankly I'd be fine with them turning out correct, considering the alternative those still fighting it generally have in mind...
