The European fighters who battled Isis – and were abandoned by their governments

Foreign fighters are returning from the battlefield — not Islamists but the Americans, Europeans and South Americans who fought to rid the world of Isis. But for all their bravery, their homecoming is a tricky one because their home countries do not want them back.

I have now interviewed more than a dozen volunteers. Many of them share similar stories of arrests and detentions. They have been stripped of their ability to travel, have their movements monitored, their bank accounts closed. One of them, an American, has since committed suicide.

One fighter, who wishes to be known as Max, tells me in an email that he has left his home country of Denmark. He had returned for a short while after enlisting for a six-month tour in the Syrian Democratic Forces (SDF) of north-eastern Syria where he fought to rout Isis from its de facto capital and caliphate.

During Max’s time there, the Danish government issued a law that made his mere presence in Syria illegal.
