In March 2025, JEF Belgium co-hosted a seminar on the future of European defence with Nikolas Kockelmann and the Federalist Society at the College of Europe.
The discussion featured UEF President and former MEP Domenec Ruiz Devesa, and Professor Dr. Frank Hoffmeister, Director of the Legal Department at the EEAS. Topics included overcoming vetoes within the current treaty framework and identifying concrete steps toward establishing a European Defence Union.
