The incidents expose a gray‑zone tactic that challenges NATO’s collective defence credibility and could lower the threshold for more aggressive hybrid actions in Europe.
The recent wave of Belarus‑origin balloons over Poland highlights a growing trend of gray‑zone operations that blend illicit trade with strategic signaling. By using low‑cost balloons to transport contraband, Minsk can probe Warsaw’s radar and air‑defence response without crossing the conventional threshold of armed conflict. This tactic leverages the ambiguity of civilian‑like objects to complicate attribution, allowing Belarus to operate under the protective veil of plausible deniability while testing the resilience of NATO’s eastern flank.
Interception presents a technical and fiscal dilemma. The balloons operate at altitudes that exceed the effective range of many surface‑to‑air systems, rendering traditional shoot‑down methods both risky and uneconomical. Lithuania’s €1 million prize for a viable interception solution underscores the urgency for innovative counter‑measures, such as directed‑energy weapons or specialized drones. Meanwhile, enhancing surveillance—through radar upgrades and satellite monitoring—can improve early detection, enabling authorities to map smuggling networks and build a stronger evidentiary case against state‑sponsored actors.
Strategically, NATO must move beyond rhetoric and treat these incursions as a "phase‑zero" hybrid threat, a concept that frames persistent low‑intensity actions as the opening moves of a broader conflict. By articulating this stance, the Alliance can justify allocating resources to counter‑balloon technologies and reinforce collective resolve. Coupled with decisive strategic communication, a proactive posture will deter future violations, preserve airspace integrity, and signal that even sub‑threshold provocations will meet coordinated, calibrated responses.
Belarusian cigarette‑smuggling balloons in the Polish airspace. How should NATO respond?

Although the objects reportedly posed no direct threat to air‑traffic safety, their presence caused a temporary limitation on civil aviation in the Podlaskie region. Despite their non‑lethal nature, these incidents represent a sustained campaign of airspace violations from Belarus, likely enabled by the broader Minsk‑Kremlin axis.
The primary objective of these incursions is twofold: to test Polish and allied air‑defence systems, and to sow intra‑alliance friction. Using balloons to achieve these aims generates several benefits. First, balloons carry lowered escalatory potential as they are not traditionally associated with military operations. Furthermore, the ability to attach payloads while obscuring their origin further complicates state‑attribution, which is already problematic in the grey‑zone context. Consequently, balloons represent a low‑cost and low‑risk asset for influencing European states, especially the frontline ones.
To answer these challenges, the Alliance should not only continue investing in air‑defence and monitoring capabilities; member states should also act more proactively. One option that is currently discussed is to neutralise the balloons by shooting them down. However, this solution has a particular drawback: the balloons fly at an altitude so high that it complicates their effective interception, making it economically unviable. In response, the Lithuanian government, for example, has offered a €1 million prize for the development of more effective balloon‑interception technologies. In the interim, prioritising the identification, interception, and sanctioning of smugglers could generate a limited deterrent effect. Such measures improve situational awareness, facilitate attribution by mapping criminal networks and potential state involvement, and, over time, strengthen the evidentiary basis for recognising Belarus as an active enabler of Russian hostile activities.
Apart from their destabilising effects, the balloon incidents highlight a rhetorical problem linked to using the term “hybrid warfare,” which continues to be an ill‑defined concept, often moulded in line with particular interests and narratives. In response, the Institute for the Study of War proposes framing such activities as Russia’s and, by extension, other belligerent states’—like Belarus’s—phase‑zero of conflict with NATO.
This terminology underscores that, through sustained below‑threshold actions, NATO is already engaged in a form of conflict with Russia, whether it formally acknowledges it or keeps it purposefully ambiguous. Such a shift in conceptualisation, though theoretical in nature, will underscore the urgency that could translate into more timely and effective policies. But conceptual clarity is insufficient if not matched by action. NATO should therefore both become bolder in its strategic communication and find practical solutions to balloon‑interception difficulties. Failure to respond with resolve risks further normalisation of malign airspace violations, as well as lowering the threshold for more aggressive actions in the future.
