Pakistan was left by its friend and ally America in the middle and then Amerca selected India as its partner against China and asked Pakistan to accept Indian hegemony in the region. Pakistan has no choice but to join China, with whom it already had an exemplary relationship. sooner India will taste American Hypocrisy. America has no friends, it has only interests, once it gets these, it refuses to recognize them.south korea japan etc didnt find it unreliable. Only pakistan did who played the doubled sided game and thought it could get away.
