As the so-called Islamic State demolishes nation states set up by the Europeans almost a century ago, IS’s obscene savagery seems to epitomise the violence that many believe to be inherent in religion in general and Islam in particular. It also suggests that the neoconservative ideology that inspired the Iraq war was delusory, since it assumed that the liberal nation state was an inevitable outcome of modernity and that, once Saddam’s dictatorship had gone, Iraq could not fail to become a western-style democracy. Instead, IS, which was born in the Iraq war and is intent on restoring the premodern autocracy of the caliphate, seems to be reverting to barbarism. On 16 November, the militants released a video showing that they had beheaded a fifth western hostage, the American aid worker Peter Kassig, as well as several captured Syrian soldiers. Some will see the group’s ferocious irredentism as proof of Islam’s chronic inability to embrace modern values.
Yet although IS is certainly an Islamic movement, it is neither typical nor mired in the distant past, because its roots are in Wahhabism, a form of Islam practised in Saudi Arabia that developed only in the 18th century. In July 2013, the European Parliament identified Wahhabism as the main source of global terrorism, and yet the Grand Mufti of Saudi Arabia, condemning IS in the strongest terms, has insisted that “the ideas of extremism, radicalism and terrorism do not belong to Islam in any way”. Other members of the Saudi ruling class, however, look more kindly on the movement, applauding its staunch opposition to Shiaism and for its Salafi piety, its adherence to the original practices of Islam. This inconsistency is a salutary reminder of the impossibility of making accurate generalisations about any religious tradition. In its short history, Wahhabism has developed at least two distinct forms, each of which has a wholly different take on violence.
