France, Poland, and other leading European nations have raised alarm over a growing wave of Russian so-called "hybrid" attacks — covert destabilisation tactics that fall short of conventional warfare, such as sabotage, disinformation, and cyberoperations. The warnings signal heightened concern among Western governments that Moscow is intensifying efforts to undermine European stability without triggering a direct military confrontation. The alerts underscore the urgency among NATO allies to coordinate responses to threats that increasingly blur the line between peace and conflict.
