"If Pakistan decides to strike down every US drone in the future, what would US do? Situation has already gone out of control for US in Afghanistan now and is forced to engage Taliban through negotiations. Any decision by US to attack Pakistan in retaliation would be disastrous not only for US interests. China and Iran would never like US presence in another neighboring country so they won’t sit quietly. Russians would have the best opportunity to avenge obviously. American public would definitely stand against its own government, this time more aggressively due to poor economy.

In above mention situation Pakistan can make life of Americans in Afghanistan a lot difficult to force US administration to reconsider their drone war in Pakistani tribal areas, only reason why it is not happening right now is presence of a weak, inept and pro-US government in Islamabad. Looking at internal politics and ever mounting public pressure against US drone attacks in Pakistan it would be prudent to assume that political situation would not remain the same in near future."

I believe it is unrealistic to think that China,Iran,Russian would support you in a situation when you strike down US drone.Americans will be in difficult situation in Pakistan if Pakistan stop his support but then there is equal opportunity that world will put more pressure on you and you will be called a "State who is protecting terrorists."
