Initiative is in the hand of India. As both Army and IK saying Pakistan will respond. So Pakistan has to manage the initiative. If the skirmishes escalate or we see a genocide after curfew is lifted:
1. Front will be Kashmir Valley.
2. Pakistan shall have to take IoK and then advance up to Himachal Pradesh and occupy it.
3. India will open Pak Eastern front and will be able to take large parts of Punjab and sindh.
4. With war on IB, Pakistan should attack from Sialkot, Shakar Garth, and gujrat to take jammu and advance to meet expederionary army in himachal pradesh.
If this war ends in a ceasefire, Pakistan then can bargain himachal Pradesh and some parts of Indian Punjab for its occupied territories.
