I know that Indians treat the issue of Saeed and Azhar as that of justice, that they be made to answer for their crimes. It is so, but their is an entirely different facet to the issue.
Liberals in both countries have always insisted that it is the establishment/deep state/vested interests that have sown seeds of enmity between the two countries. While I am still a liberal, I no longer subscribe to that view.
In my view, the establishment in Pakistan is in no different a position than that in Saudi Arabia. Left to itself, it would take decisive action against people like Saeed and Azhar. Just as the Saudi royal family knows that the Wahabbi/Salafists pose an existential threat to them, Pak government and army realize the same about rabid Mullahs and idealogues. These people are essentially anarchists, and if India did not exist their enmity would be turned towards the Pakistan state.
However, for whatever reason, these people enjoy support from sections of the masses. It could be because many Pakistanis believe they are fighting a just war against the Indian state in relation to Kashmir, or it could simply be animosity towards India. Whatever the reason, the net result is that for Indians, this section of Pakistanis is as much responsible for the current situation as Saeed, Azhar, ISI, Pak army etc.
This is actually a litmus test for the Pakistani people. Decisive action will only be taken once the establishment realizes there is no political capital invested in protecting these people. Until that time, every civilian in Pakistan who attends their rallies is Saeed or Azhar to Indians.
