Zelensky urges EU leaders to accelerate drone defence shield

European Union leaders meeting in Copenhagen this week gave political blessing to a continent-wide drone defence network, a plan accelerated by a string of Russian airspace violations that have unsettled capitals from Tallinn to Warsaw. The informal summit, hosted by Danish Prime Minister Mette Frederiksen, brought together the 27 national heads of government alongside NATO Secretary General Mark Rutte and, on Thursday, Ukrainian President Volodymyr Zelensky. Their shared conclusion: the patchwork of national air defences is no longer sufficient against a threat that moves freely across borders.

Copenhagen summit endorses coordinated drone defence

The Danish prime minister was direct in her opening remarks. "Europe must be able to defend itself," Frederiksen said, calling for increased investment in drones, counter-drone systems and a continent-wide network to respond to threats. The language marked a shift from the cautious rhetoric that has often characterised EU defence debates. Leaders endorsed the concept of a coordinated system of sensors, interceptors and command-and-control technology designed to detect and neutralise hostile unmanned aircraft before they reach population centres or critical infrastructure.

The urgency was not abstract. In the days before the summit, Denmark imposed a nationwide temporary ban on civilian drone flights after unidentified unmanned aircraft disrupted commercial aviation. Poland reported repeated breaches of its airspace by Russian drones, prompting NATO to scramble fighter jets, helicopters and a Patriot missile battery. Estonia accused Russian fighter jets of overflying its territory. Each incident tested Article 5 thresholds in different ways, and each exposed gaps in early warning and decision-making speed.

European Commission President Ursula von der Leyen framed the issue in strategic terms. "Russia tries to test us. But Russia also tries to sow division and anxiety in our societies. We will not let this happen," she said. Her proposal for a "drone wall", a network of early-warning sensors and kinetic interceptors stretched along the EU's eastern flank, has moved from concept to work programme in the space of a month. The Commission is now expected to present a detailed implementation roadmap before the end of the year.

Zelensky brings Ukraine's counter-drone experience

Zelensky's presence in Copenhagen was more than symbolic. Ukraine has intercepted thousands of Russian drones since the full-scale invasion began in February 2022, developing tactics, electronic warfare suites and mobile air defence groups that operate under combat conditions daily. "If the Russians dare to launch drones against Poland, or violate the airspace of northern European countries, it means this can happen anywhere. We are ready to share this experience with our partners," the Ukrainian president told leaders. His argument: the same Iranian-designed Shahed variants and Russian-produced Lancets striking Kyiv are the ones probing NATO's northeastern flank.

The offer of expertise is concrete. Ukrainian engineers have adapted commercial radar, acoustic sensors and AI-assisted targeting software into layered defences that protect cities and front-line positions alike. Several EU member states, including Poland and Romania, already cooperate with Ukrainian counterparts on technical exchanges. A formalised EU-level framework would standardise data formats, procurement standards and training curricula, areas where national programmes currently diverge.

Von der Leyen's drone wall gains NATO backing

The Commission president's "drone wall" concept received its most significant external validation when Rutte described it as "timely and necessary." NATO's endorsement matters because the alliance operates the integrated air and missile defence system that would ultimately cue and command many of the interceptors. A European drone shield that cannot plug into NATO's command structure would risk duplication and blind spots. Rutte's presence in Copenhagen signalled that the military side of the equation is being addressed in parallel with the political one.

The Kremlin reacted predictably. Spokesman Dmitry Peskov denied any Russian involvement in the recent incursions and dismissed the drone wall idea: "As history has shown, erecting walls is always a bad thing." The denial carries little weight in European capitals after years of documented Russian hybrid operations, from the 2015 Bundestag hack to the 2018 Salisbury poisoning and the ongoing sabotage campaigns against Baltic undersea infrastructure. The pattern is established; the question is response.

Divergent approaches to implementation

Beneath the consensus on the need for a drone shield, significant tactical disagreements persist. Frederiksen and Finnish Prime Minister Petteri Orpo emphasised speed, warning that Russia will continue probing for weaknesses. Macron argued for a broader deterrence architecture that includes long-range strike capabilities and enhanced early-warning satellites, essentially a European pillar of strategic deterrence rather than a purely defensive screen. Meloni insisted the EU's southern borders, where migration routes and instability in the Sahel create different drone threats, must not be neglected.

These differences reflect geography and threat perception. The Baltic states and Poland see Russian drones as an immediate, kinetic danger. Mediterranean members worry about unmanned systems used by smuggling networks or non-state actors. Central Europeans sit between the two. A single procurement programme that satisfies all three threat models has never been attempted at EU level. The European Defence Fund and the new European Defence Industry Programme will be tested on whether they can deliver interoperable systems fast enough.

Frozen Russian assets and the €140 billion question

The summit also revisited the proposal to use Russian central bank assets frozen in Europe, estimated at around €140 billion, to back a large loan for Ukraine. Proponents argue that Moscow should pay for the war it started, sparing European taxpayers. The legal mechanism would involve using the windfall profits generated by the immobilised assets, or potentially the principal itself, as collateral for borrowing on capital markets. The G7 has already agreed in principle to a $50 billion loan backed by these revenues.

Belgium, where Euroclear holds the vast majority of the frozen securities, remains the critical sceptic. Prime Minister Bart De Wever was blunt: "We're going to move to uncharted waters. This is very, very risky." His government demands ironclad commitments from other EU capitals to share any liability arising from Russian legal challenges or retaliatory asset seizures. Without Belgian cooperation, the assets cannot be mobilised. Von der Leyen acknowledged the concern, promising to "intensify" talks on burden-sharing. The Kremlin, for its part, denounced the plan as "pure theft."

Kremlin denies responsibility as tensions persist

Macon used the summit to widen the aperture beyond air defence. He urged Europe to crack down on Russia's "shadow fleet" of ageing oil tankers that circumvent price caps and sanctions, noting that France had detained a blacklisted vessel this week. "It is extremely important to increase the pressure on this shadow fleet, because it will clearly reduce the capacity to finance this war effort," he said. The link is direct: oil revenue buys the drones and missiles that violate European airspace. Targeting the logistics chain is as much a defence measure as buying Patriot batteries.

Romania's prime minister offered the most concrete red line. Having already seen Russian drones cross from Ukraine into Romanian airspace, he declared that the next incursion would be shot down. The statement clarifies rules of engagement that have been ambiguous across the alliance. NATO's collective defence clause has never been invoked for a drone incursion; the threshold for Article 5 remains a political decision, not an automatic trigger. Romania's stance forces that conversation into the open.
