BIAŁOWIEŻA, Poland — Michal Żmihorski, deputy director of the Institute of Environmental Protection, will never forget the morning of Aug. 1, 2023. Two Belarusian helicopters entered Polish airspace, hovering above the village of Białowieża in eastern Poland, three kilometers (1.9 miles) from the Polish-Belarusian border. The panic was palpable. “We didn’t know if the invasion had begun, if they were going to start dropping bombs,” he says during a conversation at the Białowieża-based Mammal Research Institute. The incident galvanized Żmihorski’s conviction that the borderlands should be impenetrable to enemy forces. “So that bandits on motorbikes can’t get through and start murdering people, because this is a real threat in this area,” says the longtime researcher of the UNESCO-protected Białowieża Forest straddling the Polish-Belarusian frontier. Poland shares a 420-km (261-mi) border with Belarus, 55 km (34 mi) of which runs through the Białowieża Forest, Europe’s last ancient woodland. This sprawling forest, covering an area equivalent to 200,000 football pitches, is among the continent’s top biodiversity hotspots. Consisting of impressive evergreens and broad-leaved trees, the Polish side alone is home to 900 European bison (Bison bonasus) — a species reintroduced to the forest — as well as lynx, wolves and up to 4,000 fungi species. While the specter of a military escalation by Belarus, a country that supports Russia, feels very real to some in this part of Eastern Europe, Poles throughout the country have been impacted by the war ever since Russia invaded Ukraine in 2022.

This week, Mark Leonard welcomes Camille Grand, secretary general of ASD Europe and special adviser to ECFR’s European Security programme, and Marta Prochwicz Jazowska, deputy head of ECFR’s Warsaw office and policy fellow, to discuss what the outcome of the NATO summit in Ankara means for Europe’s security. They draw on ECFR’s recent policy brief “Making defence European again” to assess whether the alliance has emerged stronger—or simply avoided a crisis.
European leaders left Ankara relieved that US president Donald Trump has reaffirmed US support for NATO and avoided announcing major troop withdrawals, but fundamental questions about Washington’s long-term commitment remain unresolved. Mark, Camille and Marta explore how Europe can strengthen its own defence capabilities while maintaining NATO as the cornerstone of collective security.
Can Europe build the military capabilities it still lacks? How should responsibilities be divided between NATO, the EU and smaller coalitions of willing states? What would a more credible European nuclear deterrent look like? And can Europe strengthen its own defence without weakening the transatlantic alliance?
