TERRES ARIDES tells a story based on a trip to Syria that a Luxembourg journalist undertook in 2019, to report on an alleged jihadist, member of the Islamic State, being held in a secret prison in the territory occupied by the Kurds, in Rojava, until the invasion of the Turkish military. The history of this fighter is unique, in the sense that he is the only converted warrior to have left from Luxembourg and to still be in captivity in a warzone. He is a perfect European citizen, he was born in Luxembourg in 1987, he grew up in Meispelt, he has a Portuguese passport. The journalist, during a trip that lasted a week but required months of preparation, passed through western Iraq into Syria, crossing the only border that is not controlled by troops of Bashar Al-Assad, to conduct an interview with the young jihadist and to launch, once back, the question of how Luxembourg justice and politics intend to deal with this case. TERRES ARIDES constitutes a starting point for a set of reflections, in particular on the role of the government, which, at this date and in this affair, has reacted little, but also on the so-called stability and social peace which reigns in Luxembourg, on questions of an ethical nature, as well as on the motivations and the future of these young wanderers in increasingly uncertain times.
