I would never be Indian and underestimate the enemy. There are plenty of professional warfighters in India and it would be at PAF and Pakistani followers detriment as well to think otherwise. PAF has also had “Yes men” political sycophant leadership which had caused it years of ruin just as the IAF may have had it before.
But that should not let it be branded professional or unprofessional solely on that basis.
Wartime performance matters a lot and
@airomerix @PanzerKiel @Ark_Angel have explained well(in various posts) the realities of their military in terms of composition, training and funding vis-a-vis their enormous size.
If anything, I would suggest that the PAF was somewhat
surprised (in terms of overestimated performance) by the IAF pilots in the air and leadership on the ground.
That doesn’t mean that the IAF hasn’t bandaged its wounds and now is equipping at a lighting footing to make up for its key strategic lackings in EW & COMSEC.
