Win and leave is the only workable strategy in the ME. We have the ability to project power at will into the area. What we seeing since 1991 is why you do not STAY in the ME.
Old Arab saying
Me against my brother
Me and my brother against the family
Me, my brother and the family against the clan
Me my brother, the family and the clan against all other tribes
Me, my brother, the family and all the clans against the Infidel
If you stay on the ground in the ME you end up trying to play policeman over tribal gang warfare going back across the last millennium.
Clearly we disagree.
My point is a premature departure threatens the longevity of any win whether it's at a local level or it includes the entire ME as you suggest in your premise.
I.e., if we leave prior to stabilizing the area any win is almost certain to be temporary and should not be considered a workable strategy.
