Overview
- Following Estonia’s request, the North Atlantic Council met on Sept. 23 and pledged to use “all necessary military and non-military tools,” calling its Article 5 commitment ironclad.
- Allied jets intercepted the three MiG-31s without escalation, and NATO said real-time engagement decisions rest with military commanders, including top commander Gen. Alexus Grynkewich.
- NATO framed the breach as part of a wider pattern that included roughly 20 Russian drones entering Polish airspace on Sept. 10 and recent violations reported by Finland, Latvia, Lithuania, Norway and Romania.
- Copenhagen and Oslo temporarily closed airports on Sept. 22 after drone sightings; Danish officials said a capable actor was likely and did not rule out Russian involvement as investigations continue.
- Frontline members hardened stances as Poland and Sweden warned they will shoot down future intrusions and Lithuania moved to speed drone shoot-downs, while Russia denied any Estonian breach and President Trump urged allies to down violators but made U.S. backing conditional.
