Tensions on NATO’s eastern borders are escalating as European diplomats delivered a clear warning to Moscow: incursions into alliance airspace will not go unanswered, including the potential downing of Russian aircraft. According to Bloomberg, the warning came during a secret meeting in Moscow where British, French, and German representatives discussed the recent incursion of three Russian MiG-31s over Estonia. European officials assessed the violation as a deliberate military tactic.
Russian officials denied any breaches, asserting that their military flights follow international rules, and claimed drones that entered Poland’s airspace were an accident. A series of violations this September has tested NATO’s resolve, as President Putin intensifies attacks on Ukraine’s infrastructure.
The United Kingdom confirmed it is ready to defend its airspace, while U.S. President Donald Trump urged Ukraine to reclaim territories occupied by Russia with EU support. European diplomats stressed that incursions must stop, with German Chancellor Friedrich Merz coordinating with Paris, London, and Warsaw, while French President Emmanuel Macron avoided specifying NATO’s possible responses.
A key element is the invocation of NATO’s Article 4, rarely used—only nine times since 1949—and twice this month following the incursions in Poland and Estonia. Denmark is also investigating Russia’s role in drone attacks.
Lithuanian President Gitanas Nausėda emphasized the need for swift action and solidarity. European officials remain cautious, wary of escalation with Moscow. Russia warned that shooting down an aircraft would mean war, with Ambassador Alexei Meskov reiterating the threat on French radio.
On practical fronts, Romania established new engagement rules for shooting down aircraft after a drone violated its airspace on September 13. Shooting drones with conventional weapons is costly and ineffective; Romanian authorities prioritize anti-drone systems, cybersecurity, and non-lethal measures as essential defense tools.
The current military reality in Eastern Europe underscores the need for strong NATO preparedness and coordination against hybrid threats, while political maneuvering with Russia remains delicate and dangerous.
