Seal JnK entirely. No one goes in, and no one goes out. Declare a state of undeclared emergency.
Ban the practice of Islam.
Remove (almost) all mosques and dargahs peacefully or anything even remotely related to Islam or even Sufism.
Make conversion to any other religion but Islam mandatory - else block rations for the families.
Remove the use of any Shahmukhi scripts etc.
Shoot at sight any journalists breaking the security cauldrons.
Relocate the children and adopt them in separate houses with Sikh parents (preferably)

This was how Kashmir became a Muslim dominated Valley. Just replace the mosques with temples, Islam with Hinduism. Hamas has a similar charter for the Jews in Israel, Islamist orgs in Kashmir had similar motives wrt non Muslims in the Valley itself. ISIS has one today. I don't feel the need to be any better, if I can establish the right of the non Muslims to live for generations to come.
This has been done in many countries as well - even recently. Myanmar, Syria, Russia (Ukraine), Sudan come to mind. It can be done.
It is a simple question. Why the Arakanese 'Freedom movement' died out and became the 'Rohingya genocide' while the Kashmiri 'Freedom Movement' is in/famous as both a 'freedom movement' as well as a 'genocide'!!! Probably Nobel Laureate Suu Kyi can give us better lessons.
