Whatever they may disagree about, Western leaders are in complete agreement about one thing: the new self-styled caliphate, the Islamic State, has nothing whatsoever to do with Islam. It's a comforting, reassuring vision for Western non-Muslims facing a massive influx of Muslim immigrants and jittery about the prospect of Islamic terrorism, except for just one problem: it's entirely false.
Barack Obama has made it clear: "ISIL speaks for no religion. Their victims are overwhelmingly Muslim, and no faith teaches people to massacre innocents." David Cameron intoned: "What we are witnessing is actually a battle between Islam on the one hand and extremists who want to abuse Islam on the other. These extremists, often funded by fanatics living far away from the battlefields, pervert the Islamic faith as a way of justifying their warped and barbaric ideology – and they do so not just in Iraq and Syria but right across the world, from Boko Haram and al-Shabaab to the Taliban and al-Qaeda."
