You locked on to 9 Jets, but didn't shoot.
You deliberately missed military targets.
Why ?
The thing is ask you military leadership to provide details of who and how many personals were present at that time . No doubt Indian media was quoting that IAF had killed over 500 militants in the airstrike last night heve if Pakistan wanted PAF could have hit targets with casualties in 10 x 1000's.
One more thing you should know that day one of war is not the day one plans on killing the elite commanders of heads of state. This has been a custom and now a customary law since time and memorial.
Hope this would satisfy your questions.
Now for the 9 aircraft that were locked and not fired upon.
What if they were shot what would that have done?
1) When an aircraft is shot down in an aerial battle it attracts attention.
2) The financial cost mounts on the side whose aircraft is shot.
3) Morale of the Air force that looses the aircraft falls.
4) Full scale war could have followed.
5) Both countries that are declared Nuclear States tend to deescalate the situation as soon as something happened because they inevitably would end up not just destroying themself or the enemy but the entire world.
6) Remember the Cuban crisis. USA had threatened to sink the Russian Ships headed for Cuba at which Russia had stated if they were attacked in openseas they would retaliate with a full Nuclear strike on Nato as well as USA. What happened then.
7) In recent times when P3 C of US NAVY was damaged in a midair collision with Chinese Air Force aircraft it was allowed to land in China as well as it was returned because if this was not done then War could have started which would have ended in a Nuclear War.
Though PAF would have loved to hit all 9 targets and claimed 9-0 victory with more that could have followed later may be same day or next but could have also shown Indian Military that IAF is not up to the standard hence would not be used in case of war which might have been avoided.
Today the wars are not swift and can not be decided as what India has face so far. If you remember the 1962 war was for 2 months, 1965 war was for few days,1971 war was for few days, Kargil also for few days.
