Yeah, right. If they were willing to help, they would have done so by now. They will not ally with an infidel against another muslim no matter what, unless the other muslim attacks them directly as Iraq did Kuwait. Any time they say they are against what their errant cousins did on 9-11, they qualify it with "but we must look at why they attacked the US" and give money to the nearest mullah, who sends a portion to Al Queda, Hamas, or some other jihadist organization.
I mean, uh, we won't exactly be able to base troops in Saudi Arabia if we bomb Mecca.
We can base troops anywhere we please, whenever we please because we have the power to do so. Better yet, just destroy all terrorist nations. Lay them to waste and forget about any nation building in the aftermath. Any friendly government we establish will only be temporary. We won't need need troops there until they rebuild in 75-100 years. If they act up again, then our grandchildren can repeat the destruction. If they are wandering the desert armed only with rocks, they won't be able to bother civilized nations.
