Nearly one year into Russia's invasion of Ukraine, its global repercussions have become indisputable as they transcended many dimensions, touching upon multiple aspects of our daily lives. Although the prospects of a conflict settlement at this stage still seem distant, the continued violence, civilian harm and risk of escalation urge us to reflect on how Europe's security and peace can be re-established. In this article, I uncover the critical security policy implications of the war in Ukraine and outline scenarios on how the war might unfold. Further, I offer pathways to restoring a European security order that is not exclusively based on deterrence but would again contain some cooperative elements. Finally, while acknowledging the severely polarized security environment, I argue that dialogue and cooperation remain conceivable and decisive in bringing this war to an end and restoring peace in Europe.
