Nope. The choice is there for them. As Pakistani call them brothers and says they have been fighting for them. But since there won't be any chance that India will let go Kashmir, may be Pakistan should give free pass to all the Kashmiri who wants to be with Pakistan and rehabilitate them in P-O-K and GB. we will happily help Pakistan in that rehabilitation, through monetary means and ensuring their safety for migration.
Land will not be given for any reason. Its too important for us. Period.
Other choice is that they can live as they have been, get constructive in region's development and welcome back Pundits if they can. Minorities who were forced out will be rehabilitated and we don't care what Pakistan do with their minorities.
Put this Kashmir issue at rest and let the people migrate once in for all.
