This is a very naive viewpoint,that economic trade between India and Pakistan will save Pakistan from the clutches of fanatics,and religious extremists.Pakistan trades with countries which are friends.India and Pakistan are not friends by any standard of imagination.While trade is one part of the story,economic interdependence is another.If by trade one has to assume,that there would be economic interdependence,that again is a pipe dream because it can happen only between nations which give MFN status to each other.Pakistan doesn't need India,or anyone else.It just needs its own people to take charge of the country and create a society that they want,be it secular or theocratic.
