The author has his wiring wrong. It is not India which is obsessed with Pakistan, rather vice-a-versa.
India tries its best to dissociate itself with Pakistan. India hates to be hyphenated with Pakistan anywhere on the world stage.
Unfortunately Pakistan can not but follow India everywhere like hutch puppy or a small kid following his dad.
eg.
India refuses to sign NPT, Pakistan refuses sign NPT, sighting Indian refusal to do so.
India refuses to sign CTBT, Pakistan does not sign it either, again sighting Indian refusal to do so.
India conducts nuclear tests, Pakistan follows... again sighting India..why ? Pakistan can make nuclear weapons but doesn't have the balls to test them, unless India tests first.
