Note: See the updated video briefing by Charles Lister, "The End of the ISIS Caliphate," published March 26, 2019 for an update on the final territorial collapse of ISIS.
After years of international intervention, ISIS was routed from its Iraqi stronghold in Mosul and from its so-called capital in the Syrian city of Raqqa last year. However, the group remains dangerous both in the region and globally. Charles Lister discusses how ISIS is operating today, and what the international community must do to combat it.
