Moslems get motivated to do something about Islamic radicalism when the violence is literally next door. That's why terror attacks in the West are so popular. The infidels are being attacked, without any risk to those living in Moslem countries. Iraq changed all that, and during the course of that war (2004-7) the popularity of Islamic terrorism, in Moslem countries, declined sharply because the terrorists were killing so many Moslems. That, in the end, is what has killed, for a while, most Islamic terrorism in Iraq. Worldwide, al Qaeda never recovered the popularity (in the Moslem world) it enjoyed after September 11, 2001. It would also be nice if the Moslem world got their act together and expunged this malevolent tendency once and for all. The Arab Spring was supposed to help but so far it hasn’t. Change is coming but don't hold your breath waiting for it to suddenly appear.
We have to help that change take place and contain the jihadis who rise up with an eye on killing Americans until that change takes place.
Sadly, pushing that change even among those we hope are on our side is very difficult.
But what's the alternative? Hoping the jihadis won't notice us if we avoid eye contact?
