Have you arrested Sayid Salahuddheen? You recently banned or take over JeM sponsored Madaris cut their funding just recently before FATF inspection. That much is your seriousness in the issue. If IK was serious, he would publicly discard support for armed militants in any country. Not the ones you favor. Pakistani duplicity has been caught countless times. This is just another googly, it'll be caught in coming months.
Some people just don't change. For some such changes are dangerous. As your top commander said
"We are fighting Pakistan's war in Kashmir and if it withdraws its support, the war would be fought inside Pakistan" Sayeed Salahudeen
Good luck trying to spin that.
