What are you even talking about? lol
For all intent and purposes, Pakistan has won the Afghan war and secured our strategic interests in the region after a long, hard, and costly war which was, at times, against U.S interests.
Pakistan will discard China or US or both if the national interests of Pakistan demanded so. For now, we are happy the way things are going
Personally, I am looking forward to U.S putting its boot down on China----it will create a more balance world order with era of super-power (US) being over, and multiple great powers emerging (China being one). Its good for regional powers like Pakistan.
