Perhaps if you can program militants using religious discussion, then you can deprogram them using religious discussion. Militants aren't EPROMs, they don't need UV light.
Although Saudi Arabia's may be more effective. The reason is basically that terrorists aren't actually programmed using religious discussion, terrorists are programmed using monkeybrain ties to other terrorists. ObGwern:
Maybe we do not share the same definition of what a "militant" is, in Saudi Arabia?
