Thanks for commenting. Yes, I agree it is a difficult subject and hard to know the best way to address it. I have done quite a bit of research on the economics of terrorism and armed conflict and my best conclusion is that what we typically do in anti-terrorism campaigns isn't working the way we think they will. A more nefarious conclusion of some people is that terrorism isn't actually a problem of terrorists, but rather a justification to continue spending resources on countering it.
