Since 2007, Russia has systematically used hybrid warfare and gray zone tactics to advance strategic aims in Europe, notably in Ukraine, Crimea, the Baltics, and Eastern Europe. These tactics include cyber and information warfare, economic leverage such as gas supply manipulations, drone incursions for espionage and disruption in EU airspace, and election interference exemplified by Romania’s annulled 2024 presidential vote allegedly influenced by Russian-linked cyber operations. The conflict in Ukraine highlights the role of drones—cheap, AI-powered UAVs used for precision strikes—indicating a weaponization of ambiguity and deniability. This approach avoids direct war, while gradually eroding democratic institutions and European resilience. Despite economic strain, Russia continues hybrid attacks aiming to exhaust Western support for Ukraine. Experts caution that while hybrid tactics destabilize, resilient democratic states in Europe can withstand them. The article concludes that Europe must strengthen technological defenses, diversify energy sources, and improve collective deterrence to mitigate the strategic challenges posed by Russia’s hybrid warfare campaigns.
