Turning back Syrian refugees isn't just wrong — it helps ISIS (Zack Beauchamp ) from Vox
"ISIS despises Syrian refugees: It sees them as traitors to the caliphate. By leaving, they turn their back on the caliphate. ISIS depicts its territory as a paradise, and fleeing refugees expose that as a lie. But if refugees do make it out, ISIS wants them to be treated badly — the more the West treats them with suspicion and fear, the more it supports ISIS's narrative of a West that is hostile to Muslims and bolsters ISIS's efforts to recruit from migrant communities in Europe."
