The Ukraine war has raised blunt questions to Europeans about how they should guarantee their security and defence. No EU or NATO state has been attacked, yet Ukraine – a partner country of both institutions which furthermore borders four EU/NATO countries – has been invaded by Russia, and this de facto challenges European stability as well as the European security and defence regime.
This brief aims to unpack how the Ukraine war has impacted the European defence debates and, in particular, the role of the European Union. It sheds light on the Common Security and Defence Policy (CSDP), the EU’s defence and security identity, and the relationship with NATO, and ends with future challenges.
