There are two fronts:
For our own people and limiting the deaths, we should withdraw, or annihilate. The gentleman's war and spreading the American brand of democracy to people that didn't ask for it isn't working. Annihilate, make those people actually afraid of us, then go from there.
The other front is that the place is shit now and we have to help maintain security because sure as hell, they can't do it themselves. A strong central leader to make the police and military unite under is needed, but there is none, so they're all aligning with who their cleric and tribe is.
On the other hand, I think we're legally required to stay there.
