How about you worry about India's foreign policy and not try to manufacture your imagination based foreign policy for the US. Shortly here, Pakistan is about to get some goodies in the form of FMS, with some additional "wish list items" by paying for it. So the US will always stand by its allies.
What you fail to understand is that the US's relationship with India is trade-based and capital oriented. With Pakistan, its very strategic. Do you know what a strategic relationship is? It is, even when you don't have money or wealth, you still have to support the strategic relationship for your own reasons. Pakistan and the US have always had rocky relationships. But they also have a relationship for over 7 decades. Even in some of the LONGEST conflicts since the WWII (Afghan War, WOT), they've still remained in a good working relationships even while the rocky terrain came and left. At this point, WOT has been almost completed, now its time for the Pakistanis to work with Aghanis and take care of this region. That's the reality and the US will fully support it like its been said many times by the Pentagon / US Government.
