i guess you ignored the fact that the US is exiting Afghanistan and its critical need of Pakistan to cooperate in that sphere,With Iran being a hostile state and Russia actively engaged in CAR domination frenzy,Pakistan is the only country which can somehow provide the US a gateway to CAR,so its Importance to US interests can in noway be underestimated,As goes for India,No country in this world not even Pakistan can progress without having better and friendly ties with India, India has much much more to offer Economically and strategically to the US in the long term,Plus the US interest of containing China military which cant be expected from Pakistan. So Both India and Pakistan have their importance for US.
I disagree with your analysis that after exiting Afghanistan, Pakistan would have no importance to US, and your comments regarding the HC's grave consequences for Pakistan, Its an empty threat with no real basis,They know who would benefit more by leaving Pakistan,The current expansion of a US embassy in Pakistan dosent points to a scenario where Pakistan could be of no worth to US..!!!
