Let me make it easy for you to understand - India doesnt live in its metros, 70% of India lives in its villages and towns, equally 70% of its economy does not come from its cities but from its rural populace - equally the whole administrative structure is saturated upto village panchayats to zillas to districts to state governments - I am sure in your desperation you will lobe at best a salvo of 10 missiles (not 1000's as some of your fanboys say, simply because you do not have more than 50 long range missiles to carry them) and this salvo will surely cripple India but it does jack to our first, second and third strike capability that will launch even before your nukes are take off from your land based missile sites.
