It's just an odd alliance we have with that country. As long as they let us use their country as a strategic launching pad in this 'war' they will remain untouched.
It's not odd. It's immoral and unethical.
Us being there guarantees a study supply of jihadi's, they know it, we know it, thus guaranteeing us lots of targets. They know it, we know it. I suppose the argument goes that we keep it up, provoking fundamentalists to act and then we kill them until there are no more but that fails on 2 counts, at least 2; one, as part of the deal we've let them export their beliefs to the US under the guise of religious freedom, thus spreading the problem, dislocating, de-cenrtalizing the problem, giving it life elsewhere. And, two, it has come, or will, come to a state of equilibrium where it is always there AND becomes entrenched, deeply, and simply goes about winning in other ways. As long as a drug king pin in the city keeps his street guys under control, the cops go after the unruly ones all the while the drug distribution and profits, remain.
Add it a 3rd, the cynical weapons sales. Absent the threat, and power, of fundamentalism, no arms race. We perpetuate, expand upon and profit from the otherwise puny, self healing problem. And a tolerable number of people around the world keep it in the headlines and keep the game going; "Security!!!!"
