Counterinsurgency in Afghanistan

I've said it before, but with things escalating rapidly in Afghanistan, it's worth repeating that Abu Muqawama (Andrew Exum, mainly) has been looking at counterinsurgency doctrine, Afghanistan, and their interactions intensively. He's your best source, in my personal opinion, but if you're not reading him, you're not familiar with the situation. (Unless you're there.) His recent conversations with other strategists about the subject is important, and he also has General McChrystal's new "COMISAF COIN Guidance" on Afghanistan, and his own comments on it.

[For those who don't speak Milspeak, COMISAF COIN Guidance means "Commander, International Security Assistance Force, Counterinsurgency Guidance." Okay?]
