Well, I will just go for the Jus in Bello and Jus at bellum stuff (as usual).
The legacy (judicial and/or moral) of going at war and the legality in conducting war.

Would be interresting to see the difference between Shia and Sunny and how this could affect COIN operations. I'm not convinced a classical COIN operation as the Surge would work in Iran or with Hezbollah.
Hezbollah was one of the first to do the shift in Lebanon to gain people support by providing social services. They do actually still challenge Lebanese state on that issue.

Shia seems to be more organised to take care of their people. Also, their tradition of dissimulation would make them in apparence more easy but in fact much hardcore and difficult to rally. But I might be wrong.

I finally managed to download it.
