Recent hybrid incidents, including drone activity affecting Romanian and Bulgarian Black Sea waters in mid-October 2026, have not triggered a formal NATO Article 4 consultation. Romania and Bulgaria explicitly declined invocation, favoring a North Atlantic Council discussion on regional security instead. The most recent prior invocation occurred in September 2025 when Poland sought consultations after repeated Russian drone airspace violations. NATO Secretary General Mark Rutte and alliance commanders have publicly assessed no imminent threat to member territory, while ongoing Russian hybrid actions such as sabotage and incursions continue to test eastern flank resolve without crossing thresholds for Article 4. A planned NAC meeting next week on Black Sea issues is expected to proceed without formal activation.
