Poland Warns NATO of Escalating Russian Hybrid Warfare

Poland's foreign minister, Radosław Sikorski, has warned that the North Atlantic Treaty Organization (NATO) must be prepared for a deadly Russian hybrid attack, as concerns mount over the Kremlin's escalating sabotage campaign across Europe. Sikorski told the Financial Times that the probability of fatalities resulting from Moscow's intensified operations to destabilize European societies is growing.

"The question is what constitutes an attack, a cross-border attack, and as long as it’s property... it’s one thing, but if people start dying, then we’ll have to have another very serious conversation at NATO," Sikorski stated. He noted that the alliance would need to make a "judgment" on how to respond, as there is no prior agreed-upon definition for such an event.

NATO's mutual defense clause, Article 5, has been invoked only once, by the United States following the September 11, 2001, terrorist attacks. Article 4, a request for high-level consultations, has been invoked by Poland and its neighbors in response to airspace incursions by Russian drones and fighter jets.

Recent incidents attributed to Russia's hybrid warfare tactics include a drone attack orchestrated by Moscow on Leipzig/Halle Airport in Germany in August. While the explosive device failed to detonate due to a faulty detonator, investigators suspect a second drone collided with a nearby cargo aircraft. In July, a Russian Kh-101 cruise missile crashed into a field in eastern Poland, creating a significant crater. Ukraine's foreign ministry confirmed the missile had crossed into Polish airspace during an attack on Ukraine, violating NATO territory.

Senior executives at European defense companies are reportedly being targeted for assassination by Russian operatives, according to officials from five European intelligence agencies. German intelligence services have also warned that the Kremlin's "shadow war" may be entering a potentially fatal phase.

Sikorski called for European nations to respond to attacks attributed to Moscow by taking measures such as closing Russian consulates, restricting the travel of Kremlin diplomats, and reducing the overall number of Russian diplomats in their countries, similar to actions already taken by Poland. He also suggested that all Russians entering the EU should be required to have biometric passports to prevent the use of false identities by operatives and supported calls for a reduction in EU tourist visas issued to Russians.

EU foreign ministers are scheduled to discuss bloc-wide restrictions on the movement of Russian diplomats and potential tourist visa limitations. Sikorski urged all EU nations to publicly attribute Russian responsibility for hybrid warfare tactics when sufficient evidence exists, emphasizing that such actions are for their own security. He also expressed support for closer ties between the United Kingdom and the EU, and indicated Poland would advocate for the UK's invitation to the G20 summit next year.
