The security architecture of Europe is currently facing a subtle yet destructive form of asymmetric warfare. By allegedly targeting critical infrastructure—ranging from airports to logistics hubs—Russia is attempting to erode Western public confidence and operational stability without triggering a conventional military response. This campaign of sabotage represents a dangerous shift in gray-zone geopolitics, testing the resilience of NATO members and forcing governments to rethink how they protect civilian assets against state-sponsored, low-attribution attacks in an increasingly unstable security environment.
