NATO Launches Operation Eastern Sentry Against Russia – Full Details & Implications (2025)

NATO has officially launched Operation Eastern Sentry following a series of Russian drone incursions into the airspace of Poland and Romania. The operation aims to bolster the alliance’s eastern defenses, protect member states, and deter further provocations. This article explains the why, how, and impact of this strategic move in detail.


What Triggered Operation Eastern Sentry?

  • Drone Incursions: In early September 2025, multiple Russian drones entered Polish and Romanian airspace. The drones were capable of carrying explosives, but no casualties were reported.
  • Polish Response: Poland activated NATO’s Article 4, which allows members to consult and take collective action when security is threatened.
  • Romanian Response: Romanian F-16 and Eurofighter jets intercepted a drone that entered their airspace during Russian attacks on Ukraine.

These incidents signaled an urgent need for a coordinated NATO response, rather than individual state action.
