Did they think about before starting a series of sniping at LoC?
Now what's happening?
I too thought they wouldn't start this thing but we must remember it's Pakistan we are talking about.
Pakistan army (there are no terrorists or jihadis, only Pakistani army) has developed a decision matrix with possible Indian responses based on historical Indian short term and long term reaction and essentially have bet on the predictability and structural weakness of the Indian response escalation and follow up matrix.
Historically, every time there has been a peace process or a peace initiative, the government at the center orders the IA and any other entities to "go slow", essentially curtailing up Indian army's freedom to respond. be it 1995-96 under IK Gujral, 1999 under Vajpayee, 2003-04 under Vajpayee, 2006-08 under Manmohan Singh, 2013-14 under Manmohan Singh, 2015-2016 under Modi, orders always go out from PMO and CCS to limit retaliation to ostensibly prevent a derailment of talks. PA is fully aware of this, and has always positioned itself to take maximum advantage of the political pressure on IA to inflict severe losses without actually crossing red lines.
Next, even if the decision matrix fails and there is an escalation, PA has over 30 years experienced that all it is required to do to end the Indian retaliation is have a call at DGMO level and request a ceasefire or a return to ceasefire and profess its good intentions, and then lie low for a couple of days to a week. Think about the sniping of IA troops by PA. As soon as the counter sniping of IA got too heavy for PA to handle, they requested IA to stop sniping duels on both sides. And in face of disbelief, IA agreed. Invariably Indian response dies down, and PA gets away scott free (yeah, the heads we bring back are nothing more than meaningless trash for PA, they couldn't care less about their men. Ghairat and PA's perception amongst its population is the only factor for PA).
Its bewildering to see the IA fall for the same ruse again and again and again. As they say, fool me once, shame on you. Fool me twice, shame on me.
Indian army and the political establishment has over 30 years behaved in a way that incentivizes PA to attack IA without any major consequences. What did IA believe the conditioning of IA's behavior on PA would have been? Essentially you have allowed PA to hit you with impunity. Now suffer the consequence.
