Drone incursions and sabotage across Europe signal hybrid warfare escalation

A series of drone incursions and sabotage incidents across Europe—including drones over Zaventem and Leipzig airports, arson attacks on arms suppliers in Bulgaria, Italy, and Estonia, and a Russian helicopter incursion into Polish airspace—indicate a coordinated hybrid warfare campaign. The pattern suggests state-sponsored activity, though attribution remains unconfirmed. This escalation raises security concerns for NATO and European infrastructure.
