Europe’s post-Cold War security order is over. Russia’s war of aggression against Ukraine has shattered the foundations of trust, cooperation and territorial security on which the European project was built. At the same time, the current critical juncture offers an opportunity to rethink Europe’s security architecture before others shape its future.

Finally, it provides with a few constitutive elements of a new “multidimensional” and sustainable European security architecture.
