Good thing that I’m not POTUS.
I start dropping nukes on them until they stopped their murdering ways.
They have had 1400 years to get this show on the road. It will not stop quickly.
I would take a different approach.
I’d carpet bomb them with scripture and audio recordings in their language of the gospel.
Everytime they abused Christians, I’d send so much scripture into their land, they wouldn’t know what to do.
