Salafi-Jihadism ideologically underpins both the Islamic State and al Qaeda. Its adherents seek a world of domination in which all others either share their beliefs, or kneel in submission to them. But Salafi-Jihadism has an easier definition: evil.

I note this in light of the ISIS-related murder last week of two Norwegian tourists in Morocco. 28 year-old Maren Ueland and 24 year-old Louisa Vesterager Jespersen were camping in a tourist spot when a cell of ISIS fanatics decided to murder them. A verified video of one of the women’s murder shows her brutally inefficient decapitation.
