This Liber Amicorum, which pays tribute to Gilles de Kerchove, EU counter-terrorism coordinator from 2007 to 2021, takes stock of what has been achieved in this field in recent years and looks at the challenges ahead. After an introduction tracing the recipient's background, the first part looks at different aspects of cooperation within the European Union, ranging from the European arrest warrant, to the protection of fundamental rights and the role of certain EU institutions or agencies. The second part deals with cooperation between the EU and the rest of the world, both with global organisations and with specific States, such as the United States. The third, cross-cutting part brings together various contributions relating to the Islamic State, the financing of terrorism, victims and new technologies. The book concludes with a fourth part on prevention, the fight against radicalisation, values, freedom of the press and literature. The authors come from various parts of the world and present a wide range of profiles, including prominent political figures, EU officials, academics, magistrates and journalists.
