Members’ Question Time: is NATO’s eastern flank battle-ready?

Join us as Katja Bego, Senior Research Fellow for the International Security Programme examines whether NATO’s eastern flank is prepared to respond to evolving threats. Submit your questions in advance.

Event date and time: 1 October 2025 — 13:00 TO 13:45 BST

Event location: Online

In recent weeks, Russian drones have crossed into NATO airspace, with incursions into Poland and Romania, and Russian MiG-31 fighter jets violating Estonian airspace, testing the Alliance’s resilience and preparedness. These provocations, alongside the Zapad exercises conducted in Belarus, have prompted NATO to launch Operation Eastern Sentry to strengthen forward defence and reassure eastern member states amid intensifying Russian pressure.

However, questions have been raised around the readiness of NATO forces on the ‘eastern flank’. As Europe continues to rearm, the threats to its eastern border appear to be at their most heightened in decades, with Russia escalating its hybrid activities across Europe and growing uncertainty over whether the United States will fully commit to defending NATO’s eastern flank under Article 5.

Join us as Katja Bego, Senior Research Fellow for the International Security Programme, examines whether NATO’s eastern flank is prepared to respond to evolving threats, what these developments mean for deterrence and forward defence, and how the Alliance can maintain cohesion in the face of ongoing Russian pressure.
