This article states that the US has been blackmailed by Pakistan. You state that you agree with this article. I still don't know what Pakistan is supposed to have received. What was the US supposed to have been blackmailed into doing or not doing?
Using the fear of his being overthrown and the nukes falling into islamists hands, he has stymied the US by saying he's cooperating while providing a hideaway for the jihadis. He claims he doesn't know where they are. Maybe he personally doesn't, but his army certainly does and he commands the army. Forestalling action by the US against alqaeda in Pakistan itself is the first consequence.
