The death cult has been spreading across the globe since 622 A.D, primarily by the sword.
It has always been a religion of war, conquest and slavery.
ISIS is following the example of their prophet and his instructions in their book. There can be no peace until there is only Islam or no Islam.
Mad Mo made it so.
There will still be no peace if there’s only islam because when there’s no infidels around to slaughter, they eat each other alive, as we see with the Sunni’s and Shi’ites.
