In the third millennium, the world is witnessing a growing gap between the development of technology - which has an exponential trend - and the development of legal and political structures - which has a linear trend. This gap, then, intertwines with the gap between Westernization and global Democratization. Europe, therefore, is facing new geopolitical threats that require, among other things, a rethinking of the role of the European Legal Scholar. The Author reframes this role starting from a reinterpretation of Legal Nihilism. On this basis, the Author argues that European constitutional doctrine should now focus primarily on the concrete conditions for the protection of European interests and values, starting with the military defence of Europe within the Atlantic Alliance. The cultural, political, and technical perspectives of European Defence are then examined. The wars and geopolitical crises of the 2020s led to a rapid Politicization of the European public sphere, which responds to the crucial interest of the entire West. All things considered, Democracies are proving to be far more resilient than expected.Ciro Sbailò is Full Professor of Comparative Public Law and Dean of the Faculty of Political Science and Psychosocial Studies at University of International Studies of Rome - UNINT.
