Can people calm down? Response will come at a time and manner of our choosing.
This is not a case of hurling a rock onto the other side. Their air defenses and missile defenses are up. If we want to hit hard with effect and ensure that we can manage the situation, there is no need to rush it.
I can guarantee, Indian security is in a state of despair. They know that the only thing left in their arsenal is pitching missiles from standoff ranges as they cannot take on Pakistan in the air or at sea.
Pakistan needs to give a cold, calibrated response, nothing rushed. "Revenge is a dish best served cold" applies all the more here. Make them wait, nervously, profusely sweating, expending massive resources to sustain their state of readiness.
