ISIS could continue radicalising for years after battlefield defeats, senior US general warns

Isil could continue to inspire home-grown terrorists for years after it is defeated on the battlefield, America’s second most senior military officer has warned.

General Paul J. Selva, vice chairman of the US joint chiefs of staff, said the terror group’s ideology could continue to have an impact because so much radicalising content is already online.

He warned nations in the anti-Isil coalition, which includes Britain, that “Isis 2.0” could emerge unless they tackle the real drivers behind extremism.
