In this paper, Marek Gallo examines the European Union’s approach to hybrid warfare, particularly following the Russian annexation of Crimea in 2014. It begins by defining hybrid warfare, exploring its historical context and contemporary implications for security. The analysis highlights the EU’s strategies, including the creation of institutions like the Hybrid Fusion Cell, and assesses their effectiveness. While recognising the dual role of the EU in utilising soft power alongside NATO's hard power, the paper also addresses the challenges posed by geopolitical ambiguities and the necessity of building trust among member states. Furthermore, it emphasises the importance of enhancing the EU's capabilities, as articulated in the Strategic Compass of 2022, and proposes recommendations for strengthening resilience against hybrid threats. The conclusion calls for a proactive stance in upholding international law and engaging civil society, reinforcing the EU's position as a key player in addressing hybrid warfare in a complex security environment.
