Any war or skirmish is done to achieve a objective, which often leads to either peace of further escalations, with doing nothing we will achieve nothing.
If Indians are hinting towards a full scale war in case of Pakistan's response than why would we take their bluff at face value ? a bluff can be just a bluff, given we see that India is no position to achieve Air superiority over Pakistan's air space, even if the war prolonged they won't be able to push deep. But in a escalation at least we will see some major treaties and agreements that will be signed by both sides, that could then result in lasting peace, Indians think Pakistan is weak and can not defend itself, Indians can just roll over every time a attack happen, you let them get through with this without repercussion and you are setting a dangerous trend, If last night action is what Pakistan Govt/Army see as some sort of Victory than sorry they have to get back to dictionary.
