In Northern Syria tens of thousands of women and children are now living in squalid, overcrowded camps. Thousands more military aged men have been corralled into Kurdish jails. Hundreds of them had left their homes in Europe and America to join the militants.  Publicly, United States President Donald Trump has called for countries to take responsibility for their nationals who joined ISIS in Iraq and Syria and return them home. But how is America handling its extremists? A retired former probation officer has lead a deradicalisation programme in Minnesota with a local Somalian community. Can the results be used to counteract the threat of ISIS ideology? James Haines-Young speaks to The National's correspondent Stephen Starr, along with Nikita Malik from the Henry Jackson Society and Colin Clarke from the Soufan Group in New York to find out what the strategies and options are.
