1. They are being punished.
2. The moment you bomb their Cantonments, as suggested by you, the war expands to bombing our cities and towns. Now, why would India, with an economy that is doing well, do that?
My alternative suggestion, which I think is what is happening, is that the military pressure must be kept up. This is being done by the undermentioned three ways:
1. IAF, being weapons free for all practical purposes, will be used to strike other targets as and when the GoI wants it done. Till then, the weapons free status and the enhanced sortie rates will keep them busy.
2. IA, since it dominates the LC, can, at will hit targets on their side for any and all transgressions.
3. IN, having being deployed in Arabian Sea and what can literally be called some nautical miles away from Pakistan (within a couple of hours to get in range) must continue its posture of heightened state of alert. Unlike the popular misconception that Pakistanis try to peddle of being able to keep an eye on the waterfront as far as Kerala, the airspace and the seas are denied to them the moment they reach any where in proximity to the IN. I can mark the same on map but it is not prudent to do that as of now. IN has 'eyes' on every nook and corner of Pakistani coastline as we speak.
Concurrently, we must continue our diplomatic offensive. Pakistanis are very happy over the Kashmir reference in OIC and are claiming it as a sort of victory.
Heaven knows, only fools can do that. Imagine having to boycott an organization that they created as the organization failed to accede to their demands to un-invite India from the meet. While the narrative of 'Muslim solidarity' has to be portrayed, the situation remains quite different.
And with the proof of F-16 use being given to US, how long do you think will it take India to make a dent in that inventory without actually having to risk platforms or lives?
But for how long. How long can we maintain this tempo of military readiness on the front lines? Won't that eat into our budget? Won't the army eventually go back into the barracks? Wouldn't it wear out the airforces spares and reduce their availability? once the military goes back terror attacks would again increase.
