"Pure Mohammadan Islam”: This is what ISIS, Daesh in Arabic, promises to deliver once the caliphate has defeated "Infidel” enemies and secured its position. The promise is at the core of its propaganda, including in cyberspace. Its recent blitzkrieg victories and high-profile beheadings are not the only reason ISIS has attracted universal attention. Perhaps more interesting is Daesh's ability to seduce large numbers of Muslims across the globe, including in Europe and the United States. It does so with an ideological "product” designed to replace other brands of Islamism marketed by the Muslim Brotherhood in Egypt, the Taliban in Afghanistan and the Khomeinists in Iran. Daeshism, to coin a phrase, also aimed to transcend the ideological hodgepodge marketed by al Qaeda franchises.
