To much assumptions, try to stand on you feet to face the challenge.
And its dropped on your post :p
Getting back to topic, given the strengths of both nations, it doesnt make sense to escalate to war.
I assume, that even if india goes for surgrical strikes it will be very very limited and precise in nature.
And in similar way the reaction from pakistan will be precise and limited to disallow indias adventure into its soil.
Both the countries dont want to get into full scale war or a kargil like stand off.
Here India might also play smart game by involving US to get the strikes done on name of war against terror.
