We can't solve their underlying problems, they have to do that. Development has done little to decrease the level of conflict in the majority of conflict zones where development was implemented as a line of effort. Capacity building only works if those we're training have the will to fight (they believe in what they're fighting for). If we believe ISIL is a real threat to our national interests, then killing on a larger scale would seem appropriate. Historically higher levels of violence have worked for non-Western countries in many cases. I don't dismiss an enduring political solution, but I do question our ability to facilitate or impose one, so again if it is in our national interest to degrade ISIL as a threat to our interests, killing them on a larger scale than they can recover from would seem appropriate. We may be able to shape what comes next, we won't be able to control it.
