Yes, Pakistan is an untrustworthy “ally”. Yes, Bin Laden needed to be taken down. No disputes there.
However, sovereignty still means something. If, lets say, a N. Korean rocket were to land on U.S. soil & fail to explode — would the U.S. feel compelled to simply return it to N. Korea? Or, at least, to just bury it, without letting anyone else look at it? Would you simply overlook the incident — ignoring the intrusion into your sovereign space?
Sovereignty only applies to the Pakis when they want it to.
When Taliban and Al Quaeda are harbored in their hinterlands they disclaim sovereignty and take no responsibility.
When Bin Laden is under their noses, they disclaim sovereignty and take no responsibility.
Can’t have it both ways. Either we hold them responsible for harboring terrorists, or we clean up their mess.
