I believe Doval and for that matter anyone with experience in Kashmir theatre understands that any move on Article 35A and/or 370 will require preparation for the worst case scenario: a full blown civil war.
Now analyze the force build up over the past month in light of this worst case scenario. 40,000 paramilitary troops in support of Amarnath Yatra, to be freed up by Aug 15. Additional 10,000 paramilitary units called up past week and now the additional 25-28,000 troops ordered into Kashmir. That's roughly 75,000 CAPF troops available from as early as next week.
Now consider also the additional Indian Army infantry units that have moved into Kashmir since mid 2016. As many as 30,000 additional troops we're mobilized into Kashmir theatre in 2016-17. If I remember right, another division worth of troops were dispatched in 2018. I'm assuming another division worth to have reinforced Kashmir theatre post Pulwama. That adds up to 60,000 additional troops from the normal troop levels of 2009-2015.
Overall a combined increment of 135,000. That brings the total fighting capable force strength to near historical highs seen in late1990s, when the militant figures were in 2000-4000 active and roughly 2000-3000 EKIAs.
This leads to the question: why does the government want such massive numbers for a militant strength of 100, unless of course the government has reason to believe that situation is likely to head south in short order and number of hostiles are likely to climb beyond the current 90-120.
I can't be absolutely certain, but such large numbers of troops should enable the GOI to sever and isolate individual districts of Kashmir, something vital when faced with a civil war type situation.
