It is too late awareness. The threat assessment done by you is very late. Any misadventure by Pakistan will be responded by all three sides whether you like it or not. Taking the cue from indian retaliation, think if Iranian forces also do their own kind of operation inside pakistan territory to take avenge for the suicide attack on their convoy the same day on Indian, and they able to achieve success then it is an open case for both the armies (indian and iranian) to collaborate and escalate it for common cause of eliminating the common non-state actors in pakistan which has considerable support in pakistan.
Just think about it.
