If you still miss us, then as a initial step from Pakistan, the most easiest and realistic approach would be Visa Free Access for citizens of both countries for different set of time-frames for different classes of people. Like for students it would be given years of time to stay in a country, for businessmen it would be for months, and for travelers it could be up to 30 days of permission to stay in a country under Visa Free Access policy.
Visa Free Access policy can be formed as a token of brotherhood as once we were same country when both country had one philosophy.
But that is only possible if we do not have BAL and if you have a stable condition without bombing issues/
+ more and more business and strategic alliance.
