America always think in their national interest, when Russia was threat to them they helped pakistan to train terrorists to counter russian threat, now they r scared by possible threat from china, and they will help India to counter chinese threat (we have helped US at the time of Tibet problem). pakistan will leave US and join china, but when relations between china and india improves, pakistan will again join US (if it exists, US will try to destabilize pakistan for its support to terrorists).
