Never is time a constraint on retaliation. In fact, the best is always later. As the enemy does not expect it and has the guard down.
But with the previous political ownership of the strikes in 2016, the GoI today has boxed itself in. It has to act overtly and take a political ownership of the same in order to avoid paying a cost in elections.
Due to snowed out conditions and launch pads being empty, I do not foresee any land incursion. Covert strike at terror infrastructure in Pakistan can not be publicly owned. The only option that remains is, and here I am speculating, perhaps a stand off strike with Heron TP? This permits Pakistan to say nothing took place thereby easing the pressure on them to launch a war yet allows India to retaliate and take political ownership
Let us see what transpires
Do both; big loud strikes now, and when the weather is right - pounce on territory.
India needs to start viewing Pakistan from a 24/7 proactive conflict lens rather than a defensive conflict to occasionally manage during flareups.
