first off, this is a question, not an argument. I'm well aware of your prowess and take this opportunity to learn from you
Having said that,
If your above assertion stands true, then how do you explain Chinese troops buildup in Gilgit/Chiltral/Kashmir region about which India was so belligerently howling about?
Pakistan, and its existence is a first line of Defence of sorts for China, if Pakistan is compromised, then China will loose a chief and imminent ally. China's long term strategic goals are highly dependent on Pakistan's security. This includes but is not limited to China's foothold in CIS, Gulf and energy corridors that would propel China to global dominance. If Gwadar, Karachi and Pasni is compromised, then Hambantoto is suffer the same fate, thus putting a brazzen end to Chinese presence in Indian Ocean. Surely the Chinese will not sit back and watch in the event where Pakistan is being battered (for the sake of argument)?
While China will exert diplomatic pressures via UN, it is not unlikely that if Pakistan is unable to surmount an Indian attack, it will indulge in military action against India. This is why China has gone on to say that 'Pakistan is our Israel'.
Would appreciate your comment on these 2 points of mine. Thought provoking posts of this thread by you. Bravo!
