Romania Expels Russian Ambassador and Invokes NATO Article 4 After Confirmed Russian Drone Strike on Galati Apartment Building

BLUFBucharest's decision to expel diplomats while withholding formal Article 4 invocation preserves escalation leverage but tests whether calibrated responses still deter further Russian strikes on NATO territory.

Romania's Defense Ministry confirmed on May 31 that Galati wreckage bore the Cyrillic inscription "ГЕРАНЬ-2" and engine components matching previously catalogued Russian Geran-2 drones 12. The drone struck a 10-story Galati apartment building at approximately 2:00 a.m. on May 29, injuring two people; President Dan expelled the Russian consul general in Constanta and closed that consulate, while Newsweek reported the Russian ambassador was also declared persona non grata, a claim Ukrainska Pravda's account did not include 34. Foreign Minister Toiu stated the incident meets criteria for invoking Article 4, but the Kyiv Post reported Romania had not formally triggered that provision as of May 31 35. Putin denied responsibility, stating "nobody can know the origin of the drone" 1.

Analysis
The forensic confirmation eliminates Russia's deniability, with France 24 and Kyiv Independent filing original reporting corroborated by secondary outlets without contradiction. Romania's expulsion of the Russian consul general and closure of the Constanta consulate mark the alliance's most direct bilateral diplomatic retaliation for a drone incursion on NATO territory. The gap between Toiu's public statement that Article 4 criteria are satisfied and Bucharest's decision to withhold formal invocation reflects calculated management of escalation leverage and alliance burden-sharing politics. Coordinated allied condemnation is rising, but Bucharest may primarily be using the forensic confirmation to extract bilateral security guarantees and air defense deployments rather than driving toward formal consultation.
