Russian Hybrid Pressure on Europe and NATO

Reports describe a broader pattern of suspected Russian sabotage, cyber activity, GPS interference and critical-infrastructure pressure across Europe, alongside NATO air-policing responses. The Arctic Shield exercise in Greenland demonstrates parallel allied efforts to improve High North interoperability across land, maritime, air, special-operations, drone, medical and logistics missions. Attribution and the 'undeclared war' framing remain contested, but the activity is relevant to alliance resilience, deterrence and escalation management.
