While the United States and Russia, two historically antagonistic superpowers, manage to sit down at the same table in Riyadh to negotiate a solution to the Ukrainian conflict, Europe, meeting in Paris, then in London, is locked into a belligerent and disconnected posture. The European Union finds itself in a position of withdrawal in the face of the Ukrainian crisis, while the United States and Russia are joining forces to negotiate and decide on the end of the conflict. Despite its geographical proximity and economic ties with Ukraine, the EU is struggling to establish itself as a leading strategic interlocutor. This highlights the limitations of its common foreign policy and its inability to unite around a single voice on crucial strategic issues.
