Can you give some concrete examples of how Pakistan has outflanked India vis-a-vis its relations with the US in the recent past.?
I for one disagree with your argumentation, as there are no permanent allies or foes in geo-policies, with US relations being normalized with Iran, India coming as global power, Afghanistan as US alley, Pakistan increasingly going towards China, I foresee rapidly changing geo political considerations, how much Pakistan weighs in US calculations is being over estimated in your calculus. If the F16 and NSG sagas be as an example of things to come, I think Pakistan's leverage vis-a-vis the US probably in the going down trajectory.
Anyways this is my understanding of the situation, maybe I have got it completely wrong
