Assessment of the Limitations of the EU’s Guarantees Regarding Ukraine’s Security and Territorial Integrity

This analysis critically examines the European Union’s security guarantees for Ukraine as of 2025, amid ongoing conflict and geopolitical tensions. Despite ambitious diplomatic efforts and increased defence spending, the EU faces significant economic and military challenges that undermine its capacity to ensure Ukraine’s security and territorial integrity.

Economically, the EU struggles with sluggish growth, structural inefficiencies, high public debt, and trade deficits, particularly with China, limiting resources for sustained military investment. Militarily, the EU’s fragmented forces and reliance on NATO contrast sharply with Russia’s extensive, war-driven military production and strategic nuclear capabilities.

The war in Ukraine demonstrates the increasing prominence of drones and missiles, areas where the EU lags behind both Ukraine and Russia in production scale and innovation. Furthermore, the shifting global order towards multipolarity and the strategic alignment of Russia and China further constrain the EU’s role as a formidable security actor beyond its borders.
