Pakistan would become Iraq^10 if the US destabilizes it, and stays put. But what if they destabilize it, and then leave ? Pakistan would agains remain Iraq^10 except only no more NATO troops to shoot at. So they will shoot each other.
No its not like that. If Pakistan becomes de-stabilized, then you and your country also have to shoulder the instability. Kashmir will immediately become hot (as well as other parts of India). Taliban type insurgency in Afghanistan will get overt support from Pakistan (there won't be a central authority, autonomous groups supporting multiple agendas)....in the end not a good thing for ANYONE!
