"'The lack of consensus over what to do with these individuals will continue to be a security threat and potential source of the group’s resurgence,' said Josh Lipowsky, a senior researcher for the Counter Extremism Project. 'ISIS now calls for its followers to support the larger, metaphorical Islamic State by attacking opponents of its ideology. For example, Uslan Khan’s attack at the London Bridge last month specifically targeted a group that works with radicalized prisoners.' According to Lipowsky, this strategy allows ISIS to be less centralized and focus its efforts primarily on propaganda. 'ISIS doesn’t have to coordinate – or pay – these lone wolves but can claim these individuals as soldiers of the caliphate while sowing fear that ISIS could strike anywhere,' he added."
