NATO and the CSDP after the Ukraine War: The End of European Strategic Autonomy?

Abstract

Abstract The paper debates the impact of Russia’s invasion of Ukraine on the relationship between the North Atlantic Treaty Organization (NATO) and the European Union’s Common Security and Defence Policy (CSDP). It argues that the invasion has changed dramatically Europe’s security landscape, carrying major implications for both organizations and their relationship. After its withdrawal from Afghanistan and deepening frictions between the US and its European allies about burden-sharing, the war instilled a new sense of purpose into NATO, placing renewed emphasis on its core functions of territorial defense and deterrence. However, the war was also a reality check for the EU, raising important questions about the future of the European security architecture, the Union’s role within it, and its relationship with NATO (hereafter also referred to as the Alliance). The aim of this article is to try to answer some of these questions, by providing an initial assessment of the impact of the war on the relationship between NATO and the CSDP, and to sketch out potential avenues for strengthening the EU’s role in transatlantic security. More specifically, the paper will try to answer the following questions: what are the implications of the conflict on the Alliance? How did the war impact on the CSDP and the Union’s aspiration to strategic autonomy? Where is EU-NATO cooperation heading as a result of the war? Will the conflict ramp up cooperation between the two organizations or will European defence efforts be channelled mostly through NATO? Will EU leaders grab the momentum created by the war to further institutional integration also in security and defence and or will the war turn into another missed opportunity to promote a more effective burden-sharing in transatlantic security?
