We have destabilized the Taliban but when we leave, they will take over again. So we've given ourselves a 10 year reprieve before doing it all over again. I figure we'll keep a Navy task force there and bomb targets to keep the terrorists weak, but not be successful in installing/maintaining a stable government. These Islamists aren't going away. They still want to reestablish the Caliphate and conquer the world. We are going to be like Israel and be in perpetual war until the oil dries up or the Middle East is nuked. That is the quandary with wars there; unless we stay there permanently to baby-sit, the crazies are always going to slither back and cause problems.
