Adam Shatz is the contributing editor at the London Review of Books. He lives in New York. In this article he says

‘The attacks in Paris don’t reflect a clash of civilisations, but rather the fact that we really do live in a single, if unequal world, where the torments in one region inevitably spill over into another, where everything connects, somethings with lethal consequences.  … For all its medieval airs, the caliphate holds up a mirror to the world we have made, not only in Raqqa and Mosul, but in Paris, Moscow and Washington.’
