A series of drone incursions into NATO countries has put Europe’s defenses to the test, with Russia probing the vulnerabilities of the alliance and signaling its increasing focus on expanding its war beyond Ukraine’s borders. The most recent wave of drone activity, which began on the night of 9–10 September, involved several drones that crossed into Poland, triggering airport closures and a series of security responses across Europe.
The Incursions and Poland’s Response
On the night of 9–10 September, while I was in Kyiv, Ukraine, under air alert due to incoming Russian missiles and drones, reports began to emerge of a significant number of drones heading westward. These drones crossed the border into Poland, with Rzeszów airport in the southeast of the country being the first to shut down. By the morning, additional airports in Warsaw and Lublin also closed their doors to air traffic.
Though many of these drones were unarmed, their significance was not lost on security experts. Some intelligence sources, including those in Russia’s ally Belarus, speculated that the drones could have been thrown off course by Ukrainian jamming. However, the scale and direction of the incursions point to a more deliberate Russian strategy. Poland’s border regions, crucial transport corridors for military and humanitarian aid to Ukraine, were clearly targeted by these incursions. The goal appeared to be a disruption of logistics while undermining NATO’s credibility and putting pressure on Kyiv to engage in peace talks on terms that would be highly unfavorable.
Testing NATO’s Response Times
The incursion into Poland, followed by further incidents later in the month, has exposed significant vulnerabilities in NATO’s readiness and decision-making processes. On 13 September, Russian drones crossed into Romania, where they were tracked by F-16 fighter jets but ultimately not engaged. Just days later, Russian fighter jets breached Estonian airspace and lingered for 12 minutes before Italian jets responded. This has led Estonia to invoke Article 4 of the NATO Treaty, signaling growing concerns over NATO’s ability to handle such threats.
These incidents have drawn significant alarm across Europe, but despite the growing risk, the response has been lackluster. In the wake of the drone incursions, NATO has yet to take decisive action, and there have been no additional sanctions or concrete defense measures to bolster the alliance’s defense capabilities.
Hybrid Warfare and Political Hesitancy
What is concerning is not only the drone incursions themselves but also the political hesitancy they have exposed across Europe. The pattern of Russia’s aggression began with the “green men” in Crimea in 2014, followed by the hybrid warfare in eastern Ukraine and Russia’s full-scale invasion of Ukraine in 2022. Each time, a slow or hesitant response emboldened the aggressor. Now, that same reluctance is playing out again as Europe fails to respond swiftly to the drone incursions.
Polish authorities, initially calling the drones “unidentified flying objects,” soon adopted a tougher stance, closing airspace near the Ukrainian border, declaring a no-fly zone within a 13-kilometer radius, and imposing airspace restrictions until December 9. Prime Minister Donald Tusk stated that the country was facing “an enemy that did not hide its hostile intentions,” prompting Poland to invoke Article 4 of the NATO Treaty and request security guarantees.
The Need for Decisive Action
This series of incidents, combined with the lack of decisive action from NATO, should serve as a wake-up call. The reluctance to engage in effective countermeasures, such as intercepting drones over Ukrainian territory, is a critical failure. Former Polish president Andrzej Duda admitted that Poland lacks adequate counter-drone systems, relying instead on outdated aircraft interception tactics.
The drones that entered Polish airspace were part of a larger hybrid warfare strategy, testing NATO’s weak points and pushing the alliance into a difficult position. Russia is probing for weaknesses, and so far, NATO’s responses have been slow and inadequate. As Ukrainian President Volodymyr Zelensky noted, these are systematic actions that require a collective, systematic response from the international community.
The Growing Threat
Experts warn that NATO’s lack of preparedness for incidents like these could have devastating consequences if Russia escalates its drone warfare against NATO infrastructure. The reality is that NATO countries, despite their superior resources, have not learned enough from Ukraine’s experience in dealing with drone attacks. Ukraine, with limited resources, has developed a layered defense system, while NATO countries, with far greater political and economic means, have lagged in integrating such technologies and strategies.
Without swift action to build political unity, coordinate defense systems, and streamline decision-making processes, Europe could face even greater challenges in the near future. If NATO continues to treat these attacks as isolated incidents rather than the beginning of a broader assault on its territory, the consequences for the alliance could be catastrophic.
