The sum of all arguments is that war is too costly and not feasible for either side, under ordinary circumstances. IAF is not going to be wiped out so easily and by the time India's military has lost even 10% of its fighting capacity, India will make the decision to align itself with every power interested in containing China.. the conflict will no longer be limited to 3 nations. Even North Korea who fields vintage aircraft will not be so easily wiped out in 10 or 12 hours, because no AF is stupid enough to expose all its assets at the same time. As any air force depletes, they become more defensive and the mission shifts to self preservation. Wars have been won with a good selection of the losing sides air machines still intact or intentionally sabotaged.
The only credible scenario is where Pakistan and China attack in unison and make small territorial gains to negotiate from a position of power. Even in this scenario, India will never cede its territory as long as it has global support and the military capacity to fight back.
The only scenario where I see Pakistan make any credible gains (which is perhaps what the OP desires more than depletion of IAF) is where Pakistani army absolutely dominates and rolls over all of Indias position within a day and secures all the territory that it claims, and then defends these positions with such skill and valor that the Indian forces cannot even gain an inch despite their best attempts for sustained periods of time. In this scenario, India will begin to act extremely aggressively along the lines of something we have never witnessed before, and holding India back without nukes will be impossible.
I hope it is understood that the above scenario is just a fanboys dream and would be nearly impossible to execute given previous track records adjusted with todays weaponry and balance of forces.
