Poland warns NATO eastern flank over Russian escalation threat

Polish Prime Minister Donald Tusk on Thursday warned that NATO's eastern flank faces a “highly unstable” security landscape and must brace for potential escalation from Moscow, speaking after hosting a summit of regional leaders in the northern city of Gdansk. The meeting on the sidelines of the Ukraine Recovery Conference brought together heads of government from Poland, Romania, Estonia, Latvia, Lithuania, Finland and Sweden — nations Tusk said were “directly exposed” to threats due to their shared borders with Russia, Belarus and Ukraine. Leaders convened amid mounting concern over Russia's military posture and hybrid activities along the alliance's frontier.

Warning of escalation

Tusk told reporters the participants unanimously agreed on the precarious nature of the security environment facing the border nations and pledged to coordinate their defense planning in the coming months. “We unanimously share the view that the situation is highly unstable and that various forms of escalation can be expected in the coming weeks and months,” he said, stressing that the countries would work closely together should the situation deteriorate further.

The Polish leader issued a sharp warning to potential aggressors while highlighting the solidarity among neighbors. “Let this be a warning to everyone who is planning something harmful against any of us or our countries,” Tusk said, noting that the gathering had demonstrated “complete unity and complete solidarity” in the face of common security challenges along the eastern flank.

Transatlantic ties and false flag fears

Despite uncertainty surrounding Washington's commitment to Europe under President Donald Trump, Tusk emphasized that maintaining robust transatlantic ties remains essential for regional stability. “We all share the view that transatlantic ties and the closest possible defense cooperation with the United States require constant commitment,” he said, adding that this message would be presented at next month's NATO summit in Ankara. Polish Foreign Minister Radoslaw Sikorski separately cautioned this week that Moscow might stage a false flag attack to justify further escalation, remarks that came after Russian President Vladimir Putin threatened retaliation against European countries allegedly involved in drone strikes on Russian territory.
