Abstract
This paper examines the evolving dilemma of European defence integration through the prism of the debate between “more EU in Europe” and “more EU in NATO.” It analyzes the structural, political, and strategic tensions shaping EU–NATO defence cooperation in the context of renewed great-power competition and Russia’s war against Ukraine. The study situates the discussion within broader debates on European strategic autonomy, transatlantic burden-sharing, and institutional duplication, assessing whether deeper EU defence integration strengthens or fragments the Euro-Atlantic security architecture. By exploring initiatives such as PESCO, the European Defence Fund, and the EU Strategic Compass alongside NATO’s force posture adaptation and enlargement dynamics, the paper evaluates the degree of complementarity and competition between the two organizations.
The analysis argues that the core challenge is not a binary institutional choice but the management of functional interdependence between the EU and NATO. While greater EU defence capabilities may enhance European resilience and contribute to fairer burden-sharing within NATO, misaligned political visions, capability gaps, and strategic divergences risk reinforcing fragmentation. The paper concludes that sustainable European security requires calibrated integration: strengthening EU defence instruments while anchoring them firmly within NATO’s collective defence framework. The future of Euro-Atlantic security will depend on whether policymakers can reconcile ambitions for European autonomy with the enduring strategic centrality of NATO.
