Whatever the claims of certain media outlets, the organisation referred to variously as ‘Islamic State in Syria’ (ISIS), or simply ‘Islamic State’ is hardly a new phenomenon in Middle Eastern history. Islam has been beset by violent schismatic and revivalist movements before, some conquering large territories and proclaiming ‘states,’ only to implode under their own internal contradictions or be crushed militarily by more established Muslim rulers. Perhaps the starkest example of this was the very entity originating the uncompromising brand of Sunni fundamentalism espoused by al Qaeda and ISIS, the Wahhabi-Saudi emirate of the eighteenth and early nineteenth centuries, which engaged the established powers in the Middle East in just the kind of ‘generational struggle’ today’s biens pensants say will be needed to defeat ISIS, a struggle having repercussions for the region today. It lost, and many of the reasons why suggest ISIS will lose too.
