How Syria Might End: A Reading List

I am teaching a class today in how civil wars and insurgencies end. I am also, meanwhile, writing my column for World Politics Review this week on the conflict in Syria. The following articles, then, have been on my mind as I think about how the conflict there might end:

1. Stephen John Stedman, "Spoiler Problems in Peace Processes," International Security 22:2 (Fall 1997), pp. 5-53.
2. Roy Licklider, "The Consequences of Negotiated Settlements in Civil Wars, 1945-1993." American Political Science Review 89, no. 3 (1995): 681-690.
3. Chaim Kaufman, "Possible and Impossible Solutions to Ethnic Civil Wars." International Security 20:4 (Spring 1996): 136-175.
4. David T. Mason, and Patrick J. Fett. "How Civil Wars End: A Rational Choice Approach." Journal of Conflict Resolution 40, no. 4 (1996): 546-568. 

Know of any other good literature on the termination of civil wars and insurgencies? That's what the comments section is for.
