I'm pretty sure that if Pakistan wasn't harboring Osama Bin Laden and other terrorists that continue to destabilize the region then America wouldn't have to. Pakistan has to get their act together.
Gotcha.
I can not agree with your sentiment that because Pakistan does not, America therefore has a right to fly drones into its land to indiscriminately kill.
Rights don't exist - they are merely useful fictions and are subject to "the guy with the guns makes the rules" rule.
