President Trump’s order to pull US troops out of northern Syria last week was a little like pushing over a domino: it meant that Turkey could start an offensive against the Syrian Kurds who live in that region and who they see as a terrorist threat; it meant that the Kurds, who have been a crucial ally of the West in the fight against the Islamic State terror group, had to refocus on defending their own people against the Turkish onslaught, and it has plunged an already volatile part of the world into further chaos.

IS thrives on chaos. So, could the increasing unrest in the region allow the group to re-emerge? Quentin Sommerville, the BBC’s Middle East correspondent, joins us to discuss.
