Pre-emptive war on the pakistan front
If India has to conduct Pre-emptive strikes on our western neighbor she shall have to target three types of targets in order to be reasonably sure of having decapitated the enemy .
1)The Command, control and communication apparatus of Pakistan must be struck, this shall cut the information chain and cause confusion while letting us prepare for retaliation(which will come).This shall also hurt morale immensely in th enemy nation.
2)Logistically important targets like fuel and ammo dumps, repair yards, bridges, power stations, T.V stations and other telecommunication infrastructure.This helps to stop/ delay reinforcements and reduces the enemy potential to fight a prolonged conflict.
3)Tactically important targets like PAF airfields,Radars and missile launchers(the latter shall require human intel to be extraordinarily strong to let us find the TEL's).

Pakistani Air Bases
Is it possible for us as a nation of taking out all these targets at once-YES
Is it going to be costly- prohibitively so both in lives lost and money
Assets that can be used- first a wave of LACM'S to target radars and SAM sites then send in the sukhois and mirages.
Will we still face retaliation-Yes both from outside and inside, Pakistan has the unique ability to retaliate against india by activating sleeper jihadi cells across the length and breadth of India. the first strike in any future indo-pak war will not be an F-16 firing missiles at a mig it will most probably be a car packed with explosives blowing up near western command headquarters in khadki pune.
What areas would India need to defend?
The same areas that we attack, just as Pakistan is vulnerable so are we,; any nation is vulnerable to attacks on bridges,fuel dumps, and telecoms infrastructure. we will need a robust and interlinked network of modern radar and SAM's to defend ourself.
