No Indian goods through Pakistan

Certainly.. But most things Indian that make their way into Pakistan are black market items. Those items have always been around. Most Indian films you find for example are pirated. Im not against those products...:D

And I have no problem with Indian products entering Pakistani market so long as its part of a larger package which includes settlement of all outstanding issues.

As for products going to Afghanistan, well thats a different matter. India has been trying to flank us on the western side for quite a while. Even if it hasnt been its open policy, we still cant allow an enemy to surround us.
Allowing Indians access to Afghanistan will increase their influence. It may well happen whether we give them access through Paksitan or not, but we certainly shouldnt be aiding in the process. Not unless we can manage to settle whatever grievances we have, and India ceases to be a threat to Pak intrests or security.
