The volume “From Normative Silence to Geopolitical Adaptation: The European Union and Future Geopolitical Challenges” explores this profound transformation through a multidisciplinary lens. Bringing together diverse scholars from different backgrounds, the book examines how the EU’s strategic, normative, and institutional identity has evolved in response to a new era of instability. The contributions collectively argue that the Union, long regarded as a “civilian” or “normative” power, is undergoing a gradual metamorphosis into a geopolitical actor shaped by crisis, resilience, and adaptation.
