The war in Ukraine has fundamentally changed the European security environment. The EU and its member states are committed to supporting Ukraine in its self-defence in the long-term. In recent years, the EU has become an important actor in the security area, complementary to NATO, which carries out collective defence as its core task. This raises the question of how the EU-Ukraine relationship in security and defence should be shaped. This policy brief aims to provide answers to that question. The authors firstly assess how the war in Ukraine has impacted on the EU and NATO. The next section explores the options for enhancing the EU-Ukrainian security and defence relationship. The final section is devoted to EU-NATO cooperation on assisting Ukraine on its way to future membership of both organisations. Conclusions and recommendations complete this policy brief.
