There is no doubt that for the Pakistani leadership, and especially the army, to reduce the salience of, let alone jettison, the Kashmir cause would be extremely difficult, unpopular and politically dangerous.
In Pakistan’s delusional parallel universe, victory has been claimed on two grounds: Jadhav’s death sentence was not annulled and the ICJ did not order his release. Some have even claimed that by not releasing Jadhav, the ICJ has accepted that he is a terrorist and that implicitly India is a state sponsoring terrorism!
Pulwama tragedy signals a significant escalation in terrorism in the Kashmir Valley. Given the type, target and the scale of the attack, it seems obvious that this was done at the behest of Pakistan’s Inter Services Intelligence (ISI).
