An invitation from Al Jazeera to comment on what Britain should do with returning ISIS fighters. The current international criminal justice system (CJS) is neither set up nor capable of dealing with ISIS soldiers, who have committed war crimes against civilians. Britain is one of a few countries with a CJS that can deal fairly and transparently with war criminals, taking account of the needs of victims and the balance between punishment and rehabilitation.
The International Criminal Court earned a good reputation for its work in the Balkans, but it has failed the effectiveness test in Libya, where none of the crimes against humanity have been resolved.
