Bringing up the threat of a nuclear annihilation of some portion of their core may help the moderates to realize that they are responsible for saving their religion from this radical infection.
I agree. They must change within if they are going to save themselves.
According to that one British survey, 1 in 4 muslims over there sympathize with the terrorists. The other 3 need to educate the others, as they know that their future depends on it. I don't understand why they aren't more public and active about it. Their silence and indifference says a lot to me.
