All people on Pakistani side are martyred. Civilian too are Shaheed.
There could be a way to end a part of damage done to civilians of AJK by bombardment of Indian Army. For this Pakistani Military has to plan to extend the LOC further east and north by capturing some strategic points and creating a 5-10 km buffer zone between LOC and AJK population.
1. The first step is to survey which AJK populated areas are continuously affected through Indian bombardment.
2. Mark posts and artillery positions of Indian Army on the maps, which fire at AJK population.
3. To create a buffer zone of 5-10 km, PA would need to carry out an offensive of 5-10 km into J&K and occupy or by pass Indian Army posts. This can obviously create a larger conflict in the region which can lead to full fledged war.
4. Pakistan Army should aim to capture those areas which can be comfortably supplied once captured. This means the DGMO and QMG have to sit together and brain storm for a plausible solution for the long term. Another criteria could be positions where there is less or hardly any J&K population so they can also be kept safe from military damage in the longer run.
5. If the offensive is carried out in J&K on multiple locations, it may seem a full fledged attack from all formations of Pakistan Army deployed on the LOC, but it has its advantages. In kargil war, Indian Army concentrated its manpower and resources in one region and that made it easy to resist infiltration by Pakistani forces. Opening fronts at multiple locations has its disadvantages too since resources of PA will be also be divided. Opening front one by one can also be possible. When one of the planned locations are secured, then start phase-II and start offensive 50 km or so away at a different location.
6. PAF and other paramilitary forces (GB) will be required to get involved so the secrecy that was kept in Kargil war will not be applicable. PAF will be required since after the required areas/peaks are captured, PA troops will need to be protected from IAF bombardment. PAF should also be available to provide ground strike sorties when requested by PA.
7. This Ops will be costly for PA troops even if the objective is to infiltrate a few km, capture and then fortify some locations. Defending all these extended positions will require a continuous supply chain of troops, equipment, weapons, material, ammunition etc.
India will never tolerate such a military step by Pakistan so there are a lot of chances that the matters will escalate to a full fledged war and the International community will pressurise GOP to retreat back to original positions. Pakistan will be in a fix since retreating back would mean internal humiliation from Public who will lose faith in Military and GOP. If Pakistani Army doesn't retreat instead fortify themselves in new positions and supply lines are opened, then the Kashmiris of J&K can have a ray of hope that Pakistan is willing to take practical steps for their liberation from Indian tyranny. When the sentiments of Kashmiri population in J&K are witnessed on ground by PA and reported by commanding officers back to GHQ, then further operations on the lines of Ops Gibraltar can be planned. Previously such sentiments and commitment was not considered in 1965, instead matters were taken as understood which turned out completely incorrect.
India will definitely open a new front in retaliation and the infiltration from Afghanistan/Iran will increase from western border. The damage inside Pakistan through blasts and attacks will increase.
To ensure that the operation succeeds no matter what, Pakistan can take China in confidence and request assistance of weapons and equipment from China stating that CPEC lines will be secured and offense is the best defence. Pakistan should ask for dozens of transport helicopters and thousands of protective/weather resistant military gear for regulars/paramilitary from China (as well as J-10, for lovers of J-10 on this forum, I'm not one of them). Pakistan should not ask China for involving itself militarily in this offensive since USA will then join India citing Chinese active involvement as an excuse. Mere presence of China on LAC would be enough for the time being. A portion of harsh weather military gear that India purchased for troops deployed on LAC will have to diverted to LOC. As soon as the offense starts, Pakistan should notify Turkey, Azerbaijan, Malaysia and other friendly nations that phase-I of an offensive has started to secure homeland from enemy fire and to free oppressed muslims from India.
There is a clear statement by Azerbaijan through which the Karabkh conflict has started, Pakistan can do the same in kashmir if the military top brass and civilian Govt agree to take such a step.
