That's literally like saying, Indians went to a boxing match and were surprised that punches were thrown.
I can't decide whether it's ineptness, actual retardation in the Indian military forces, mixed up with paf air superiority and a superior class of Chinese technology and doctrine, how much do we really wait these things? I actually only think that the paf are in a position to assess this soberly
Finally, imagine a scenario, what if the Chinese air force were literally to go full force on India tomorrow, they could literally roll the skies north to south.... That actually does not seem farfetched
