This sounds ludicrous in the face of what's actually happening on the ground, but this sort of stuff starts formal, overt wars. If Waziristan is out of control that's one thing, if it's out of control and acting as a sanctuary for covert ops its another, but it's quite another still if it's an open staging area for cross-border raiding including assassination attempts on the neighboring head of state. Pakistan's sovereignty comes to an end at that point.
The real difficulty, of course, is that a Pakistan openly attacked in retaliation might in turn retaliate with nuclear weapons to protect the raiders. That is just how destabilizing an Islamic bomb is, a thing that the people so blandly accepting of Iranian nuclear weapons had better think about.

I to have wondered when an Al Qaida/Taliban nuke (provided by Pakistan of course) will be used in Afghanistan against American forces. I can think it's entirely possible. I'm sure the Pakis will deny providing it to them. We'll have to nuke them back of course. Horrible state of affairs over there.
