Quelle nouvelle architecture sécuritaire mondiale ?

It is clear that we are witnessing a reconfiguration of the international order in a context marked by the return of high-intensity conflict, the rise of great power rivalries, and the weakening of multilateral frameworks inherited from the post-Cold War era.

The central question then becomes that of the modalities of a security governance capable of articulating sovereignty, cooperation and conflict prevention.
