It is far fetched ( and not my first guess) but step into India's shoes and look around you. If I had Pakistan (with wild card nukes) on my border right now I'd be looking real hard for a bigger power to pluck them.
Good observation.
What is AQ Khan's current status? Didn't Pakistan just make him apologise nicely and promise to quit giving the goodies away or did he ever face any serious sanctions?
Too True!
