Every single ISIS combatant and sympathizer needs to be rounded up and boiled in oil and there cooked remains served to pigs. The whole thing must be publicaly staged and visible on all media around the globe.
Boiled in bacon grease and fed to dogs...by women...with their ankles immodestly showing...and no face covering.
Won’t the pigs eat them raw?
No, no need for that. Just judged and hanged. The death of a common criminal. There needs to be a Nuremburg proceeding like for the Nazis.
The ones doing these crimes are well known and should be hunted for 6 decades. Often their faces are visible.
