There is a Catch 22 situation which India is in forever. While we would love to do something drastic and decisive about the troublesome neighbour, the fact is that we simply do not have an answer that sees peace at the end of the day.
The most demanded option - that of complete invasion and destruction of the Pakistani Terror State, although well intentioned and justified umbrage of our citizens, is an option that has greater costs to the results achieved, which shall still be temporary in nature.
A hypothetical invasion and subsequent destruction of Pakistani state, with barest of costs in terms of manpower, material, economy and actual destruction of own areas, will still result in the dilemma of having to vacate the territories, in which case, a disgraced and defeated army will be too weak and this will give the inherent sectarianism there to rise to fore with space for Taliban, AQ, ISIS to gain hold and then, after consolidation, get after us, or, if we continue to occupy, will allow a rallying point for the local fundamentalized population to unify in their objective of throwing India out, just like US in Iraq.
The overall costs will be thousands of times than what it costs us right now.
Nuclear Bombs across the territories is a theoretical option which will wipe off this problem ...
But that is only something theoretical
So, the only way forward is to keep the costs for Pakistan high, economic ones, that will see a degradation of their capabilities over a sustained period of time.
Much like Kautilya's famous thorn and buttermilk story.
