Four terror attacks on Friday that left scores dead across four countries on three different continents raised speculation that Islamic State had launched a concerted offensive from its Syrian and Iraqi stronghold to mark the first anniversary of its Caliphate. However, an expert on jihadist movements, Wassim Nasr, dismisses the idea that the outrages in France, Tunisia, Kuwait and Somalia were part of a coordinated campaign, and says the West still does not understand Islamic State's real strategy. In a wide-ranging interview with Mediapart, the specialist contends that Western states, including France, have themselves created the breeding ground for jihadist groups by backing dictatorships over democratically-elected popular movements.
