PROFILE: Zelensky versus Lukashenko — the ultimatum of a war leader against a Kremlin vassal

Introduction: On June 25, Zelensky puts Minsk on notice

The declaration that changed the tone of the Belarusian-Ukrainian relationship

On June 25, 2026, President Volodymyr Zelensky published on Telegram an unusually grave statement about the situation in Belarus. His phrasing was direct and unsparing: Belarus, "under obvious Russian influence," was completing the construction of military infrastructure along the Ukrainian border — roads and storage bases for ammunition and fuel that "have no purpose other than military." Ukraine, he specified, had already "sent Minsk the relevant signals about the inadmissibility of these actions." And he demanded they stop.

This is not the first time Zelensky has raised the Belarusian threat. But the precision of the information he provided — five specific border directions, the nature of the construction, the Russian context of these works — and the tone of a transparent ultimatum signal an escalation in the Ukrainian posture. Ukraine no longer pretends that Belarus is a complicated neutral state. It names Belarus for what it has become: a potential war base against Ukraine.

Portrait of a confrontation between two visions of peace

On one side, Zelensky: a democratically elected war leader, survivor of four years of total conflict, whose legitimacy is reinforced by every missile that falls on his country and every ally who stands by him. On the other, Lukashenko: in power since 1994, maintained by force since the electoral fraud of 2020, whose political survival depends entirely on Vladimir Putin. These two men represent two answers to the same question: how do you govern when war is knocking at the door?

The five axes of the threat: what Zelensky revealed

Kobrin-Kovel, Ivanove-Manevychi: the western axis

Zelensky cited five precise directions of military infrastructure construction along the Belarusian border. The Kobrin-Kovel axis points toward the northwest of Ukraine, toward Volhynia — a border region with Poland. The Ivanove-Manevychi axis follows a similar trajectory through the marshy zones of Polesia.

Both axes are geographically challenging — Polesia is a region of forests and swamps that slowed Russian forces during their attempt to take Kyiv in March 2022. But new infrastructure roads can transform these natural obstacles into corridors of advance. Building roads through marshland has only one conceivable wartime purpose: enabling the passage of heavy military vehicles.

Rechitsa-Korosten, Gomel-Chernihiv: the most threatening axes

The Luninets-Sarny, Rechitsa-Korosten, and Gomel-Chernihiv axes are potentially the most alarming. The Gomel-Chernihiv axis is precisely the route Russian forces used in their attempt to approach Kyiv in March 2022. The city of Chernihiv, in northern Ukraine, withstood encirclement at that time in one of the most heroic acts of the war's opening weeks. The reconstitution of an attack base along this axis can only be read as preparation to repeat that attempt.

The Rechitsa-Korosten axis opens toward Korosten, a mid-sized city whose capture would potentially sever communications between northern and central Ukraine. These five axes, taken together, cover the entire Belarusian border with Ukraine — this is not preparation for a targeted strike, it is preparation for simultaneous pressure along multiple directions.

Russian documents: proof that Belarus is integrated into the STO

What Russian documents reveal about Belarus

Zelensky added a detail of critical importance: in Russian documents, the military infrastructure construction on Belarusian soil is described within the context of the tasks of the so-called "STO" — the special military operation. This is no longer a Ukrainian allegation about Lukashenko's intentions. It is confirmation, drawn from Moscow's own documents, that Belarus is planned as an integral part of the Russian war against Ukraine.

Ukraine has had access to Russian documents since the 2022 invasion — through electronic sensors, prisoners, and documents recovered from the field. The quality of this intelligence has evidently reached a level sufficient to allow Zelensky to cite internal Russian documents explicitly mentioning Belarus within the framework of the STO. This is a demonstration of intelligence capability that should unsettle Moscow.

Ukrainian intelligence: 500 targets identified in Belarus

The commander of Ukraine's Unmanned Systems Forces, Robert Brovdy, has indicated that 500 targets have been identified on Belarusian territory — notably Russian installations serving as drone relay stations that attack Ukraine. These relays allow long-range Russian drones to maintain GPS connectivity and recalibrate their navigation over Belarusian territory before entering Ukrainian airspace.

Mapping 500 targets in Belarus is an unambiguous message: Ukraine knows where these installations are. It has the precision needed to strike them. It has not yet done so — but the implicit message is that this calculation could change if the situation deteriorates.

Profile of Zelensky as a war leader: the method of the direct ultimatum

The doctrine of strategic transparency

One of the most distinctive characteristics of Zelensky's communication since 2022 is his strategic transparency. Unlike diplomatic tradition, which transmits warnings through discreet channels to preserve negotiating options, Zelensky has consistently chosen to make public the warnings he delivers to his adversaries — about Russia, Iran, North Korea, and now Belarus.

This transparency serves several simultaneous functions. It informs international public opinion of the threats Ukraine perceives, creating pressure on allies to respond. It allows Zelensky to show his own population that he is informed, vigilant and actively protecting the country. And it sends a direct signal to adversaries: we see what you are doing, you cannot hide behind plausible deniability.

The ultimatum method: name, demand, promise consequences

The June 25 declaration on Belarus follows a pattern Zelensky has deployed effectively in other contexts. He names the problem with precision (the five construction axes). He cites the evidence (the Russian documents). He formulates a demand (stop the construction). He recalls the consequences (the signals already sent to Minsk). And he implies without stating explicitly that more direct responses are possible if the demand goes unmet (the 500 identified targets).

Profile of Lukashenko: the constrained vassal

A man whose survival has depended on Putin since 2020

To understand what Lukashenko does — or does not do — in the face of Ukrainian pressure, one must understand his structural situation. Since the electoral fraud of 2020 and the bloody crackdown on the protests that followed, Lukashenko is maintained in power solely by Putin's military, economic, and political support. Without Russia, he falls. With Russia, he survives — but at what price?

That price is now visible: a Russian Oreshnik missile system on his soil, Russian troops garrisoned in his bases, Wagner instructors training his soldiers, his defense industry fused into the Russian military-industrial chain, and now ammunition and fuel storage bases built on the Ukrainian border according to Russian STO plans. Lukashenko is no longer an ally of Russia — he is an administered dependency.

The Belarusian mobilization reserve: 289,000 potential soldiers

The report from the Belarusian opposition delivered to Sybiha on June 22 estimates the Belarusian mobilization reserve at 289,000 people. Add professional soldiers (multiplied by 1.5 since 2022) and the "popular militia" that could reach 150,000 members, and the theoretical mobilizable potential exceeds 500,000 people. For a country of 9 million inhabitants, this level of potential mobilization only makes sense in the context of a large-scale war.

If Lukashenko decides — or is compelled — to commit these forces against Ukraine, the consequences would be immediate: a reopened northern front, a dispersal of Ukrainian forces, additional pressure on already stretched resources. That is exactly what Putin wants — and why he has invested so much in militarizing his Belarusian vassal.

The Belarusian opposition's reaction: Latushka, witness from the inside

Pavel Latushka and the United Transitional Cabinet in exile

Pavel Latushka, deputy head of the United Transitional Cabinet of Belarus, is one of the most important figures of the Belarusian opposition in exile. A former director of the Bolshoi Theatre of Belarus and former ambassador, he left the regime after the electoral fraud of 2020 and became one of the most recognizable faces of the Belarusian democratic resistance.

His decision to deliver a 30-page report to Sybiha on June 22 is part of a strategy by the Belarusian opposition to document regime activities and share them with Ukraine's allies. This report is not an isolated political act — it is the expression of an informal intelligence cooperation between Ukraine and the Belarusian resistance, two parties sharing convergent strategic interests.

What the Belarusian opposition represents for Zelensky

For Zelensky, the Belarusian opposition is not just a source of intelligence — it is proof that the Belarusian people are not Ukraine's enemy. The same Belarusians who protested against Lukashenko in 2020 are now in exile in Warsaw or Vilnius, helping Ukraine document the regime's military preparations. This distinction — between regime and people — is central to Ukrainian communication about Belarus.

NATO and the response on the northern flank: between Vilnius and Warsaw

Lithuania: front line facing Belarus

Lithuania shares a direct border with Belarus and hosts the "Suwalki corridor" — the 100-kilometer strip of land connecting Poland to the Baltic states and separating Kaliningrad from Belarus. This corridor is considered by NATO strategists to be the alliance's most vulnerable point in any conflict with Russia.

Lithuania received on June 25, 2026 the first disbursement of 956 million euros under the SAFE program (Security Action for Europe) to finance the purchase of ammunition, missiles, and air defense systems. This disbursement is not a coincidence of timing — it fits squarely within the same dynamic as Zelensky's warnings about Belarus.

Poland: between Ukrainian solidarity and defensive preparation

Poland, despite the diplomatic crisis with Ukraine over the UPA issue, has not relaxed its military vigilance along its border with Belarus. Since 2023, it has maintained a reinforced force deployment on that border, in response to the migration crisis instrumentalized by Lukashenko and to documented troop movements in Belarus. The NATO summit in Ankara on July 7–8 is expected to address this frontally, with reinforcements anticipated on the eastern flank.

What Zelensky asks of Lukashenko: an honorable exit

The signals sent to Minsk: what are they?

Zelensky indicated that Ukraine had sent Minsk "relevant signals about the inadmissibility" of the military constructions. The exact nature of those signals was not specified — but one can reasonably suppose they include direct diplomatic communications (perhaps via Turkey or other intermediaries), warnings about the consequences of Belarusian participation in the war, and perhaps messages about Ukrainian strike capabilities against the 500 targets identified in Belarus.

By leaving open the question of concrete consequences while mentioning the 500 mapped targets, Zelensky offers Lukashenko a form of exit: stop the construction, distance the Russian military infrastructure from the Ukrainian border, and avoid a direct strike. That is the rhetoric of deterrence — not of pre-emptive aggression.

Why Lukashenko probably cannot respond positively

The tragedy of Lukashenko's position is that he may no longer control the decisions that concern his own territory. The military infrastructure construction on the Ukrainian border is described in Russian documents as part of the STO. These are not Belarusian projects Lukashenko could halt by decree — these are Russian projects on Belarusian soil that he has agreed not to obstruct. Stopping them would require directly defying Putin. And Lukashenko knows what happens to leaders who defy Putin.

The 500 targets as asymmetric deterrence

The logic of deterrence through mapping

The revelation by Robert Brovdy that 500 targets have been identified in Belarus — notably Russian drone relay stations — constitutes a signal of asymmetric deterrence. Ukraine has the capability to strike Belarusian territory. It has not yet done so at scale — but it has mapped the targets. Revealing that mapping without striking is to exercise psychological and strategic pressure without provoking immediate escalation.

This logic is consistent with the Ukrainian posture throughout the war: demonstrate capabilities, signal limits, leave the adversary responsible for escalation. Ukraine does not strike in Belarus because it does not want to open a new front — but the 500 mapped targets mean it could revise that calculation if the front situation demanded it.

Drone relays: a daily violation of international law

The Russian drone relay stations installed on Belarusian soil constitute a daily violation of international law. They allow Russian drones to cross Belarusian airspace — the sovereign space of a UN member state — to strike Ukrainian territory. The fact that Lukashenko tolerates, even facilitates, this use of his territory as a strike platform makes him complicit in those attacks under international humanitarian law.

What this means for the region's future

Three possible outcomes for Belarus in the coming months

The current situation cannot remain in suspension indefinitely. If Zelensky's 40-day campaign sufficiently weakens the Russian military position, the pressure on Lukashenko to compensate by committing his own forces could grow. Conversely, if Russia secures significant concessions in eventual negotiations, Belarusian mobilization may prove unnecessary.

The third outcome — the most likely in the near term — is the maintenance of the ambiguous status quo: growing militarization of Belarus in service of Russia, without formal entry into the war, combined with missile strikes and active logistical support for the Russian military. That is uncomfortable for everyone — except Putin, who reaps the benefits of the Belarusian base without formally bearing the diplomatic costs.

Portrait of Zelensky as a regional deterrence strategist

This June 25 declaration reveals a dimension of Zelensky that goes beyond the bilateral war against Russia. He is managing the regional security of Eastern Europe with the tools at his disposal — transparency, deterrence, direct diplomacy, and the demonstration of military capabilities. It is a role that the major EU powers should have occupied since 2020. In the end, it is a Ukrainian president at war who is playing it.

The Belarus of tomorrow: two opposing scenarios

Scenario of entry into war: regional implications

If Belarus enters the war against Ukraine — even in limited fashion — the regional implications would be immediate. NATO would need to accelerate the reinforcement of its eastern flank. Lithuania and Poland would find themselves with an active border with a belligerent. Pressure on Ukraine's logistical supply corridors through Poland would intensify. And Ukraine would need to disperse its forces across a reopened northern front.

This is the scenario Putin seeks in order to destabilize the coalition supporting Ukraine. It is the scenario Zelensky is working to prevent through his public warnings and private signals to Minsk. And it is the scenario NATO must account for in its Ankara planning.

Scenario of restraint: conditions for a negotiated outcome

In the scenario of restraint, Lukashenko maintains his calculated ambiguity — logistical support and infrastructure, without direct commitment of his forces. This restraint would be favored by Western diplomatic pressure, Ukrainian warnings, and above all the Belarusian popular resistance to any participation in a war against Ukraine. Available Belarusian opinion surveys indicate strong opposition within the population to entering the war against Ukraine.

The long-term implications for the European security architecture

A structural turning point in continental security relations

The developments described in this article are part of a broader transformation of the European security architecture. The European Union, long perceived as an essentially normative and economic power, is acquiring a real and substantial military dimension. The instruments created since 2022 — SAFE, APF, enhanced PESCO, bilateral industrial cooperation — together constitute an institutional foundation for a European defense that did not exist five years ago.

This structural change is irreversible insofar as it responds to real, documented and growing security needs. As long as Putin's Russia maintains an aggressive posture and the democracies on Europe's eastern periphery are threatened, the movement toward a more robust European defense will continue. Debates about national sovereignty, burden-sharing and national priorities will remain — but they will not reverse the underlying trend. Collective security requires collective structures. And Europe is building them.

What this evolution means for Ukraine

For Ukraine, these developments are directly linked to its immediate security and its long-term future. In the immediate term, every billion invested in European defense, every military capability developed, every contract signed with Ukrainian producers strengthens its capacity to resist. In the longer term, a solid European defense is the best guarantee that Western support for Ukraine will not evaporate with the next change of government in the United States or elsewhere.

Ukraine is not only a beneficiary of these developments — it is also an essential driver of them. Its combat experience, its growing industries, its technological innovations in drones and electronic warfare systems directly feed the investment choices and operational doctrines of the allies. Europe learns from Ukraine as much as it brings to Ukraine. And this mutual learning partnership is one of the most enduring legacies this war will leave to the continent's collective security.

The international response and the support of the Atlantic community

Allies facing the evolving situation

Ukraine's Western partners have followed the most recent developments closely. European chancelleries, NATO general staffs and allied intelligence services have integrated this information into their analyses and planning. The decisions described in this article are not taken in a strategic vacuum — they are part of a permanent dialogue between Kyiv and its partners, a technical, political and military dialogue conducted through dozens of formal and informal channels.

This dialogue has produced concrete results visible in weapons deliveries, soldier training, intelligence sharing and coordinated diplomatic decisions. The institutional framework of this support — NATO, EU, bilateral coalitions — has been considerably strengthened since 2022 and now functions with an effectiveness no one would have predicted at the start of the conflict. Ukraine is no longer alone. And this reality fundamentally changes the strategic equation facing Russia.

Future commitments: durability and depth

The durability of Western support is a legitimate question Ukraine raises regularly. Political changes in allied democracies — elections, government changes, popular budget pressures — can cause fluctuations in engagement levels. That is why Ukraine seeks to institutionalize support in bilateral treaties, multi-year industrial contracts and financing mechanisms with long-term commitments that transcend electoral cycles.

Investment in Ukraine's defense industry, pilot training on Gripen aircraft, SAFE financing guarantees over 45 years — all these decisions aim at exactly that objective: creating irreversible commitments that can only be undone by a deliberate and costly political decision. This is conscious institutional strategy. And it reflects the maturity that Ukrainian decision-makers and their partners have acquired since the start of the conflict.

The regional geopolitical context and its ramifications

A regional instability with multiple dimensions

The Ukrainian conflict cannot be understood in isolation. It is part of a broader regional geopolitical context that includes tensions between Russia and its immediate neighbors, internal dynamics within Atlantic democracies, and the calculations of emerging powers seeking to exploit Western instability. China, Iran, North Korea — all these actors are watching closely what happens in Ukraine and drawing lessons for their own strategies toward the West.

Ukrainian resistance is therefore not only important for Ukraine or for Europe. It is a global signal addressed to all those who might consider challenging the international rules-based order. If Russia obtains durable gains in Ukraine through aggression, it sends a devastating message: violating international law is profitable. If Ukraine resists successfully, the message is reversed: democracies defend their values, and aggressors pay the price.

Sanctions as a tool of systemic pressure

The economic sanctions maintained by the European Union and its partners against Russia remain one of the most significant pressure instruments available. They do not end the war in the short term, but they constrain the resources available to finance the Russian war effort, they increase the economic costs of aggression for the Russian population, and they maintain international pressure on Moscow. The renewal of sanctions for 12 additional months until July 2027 demonstrates the allies' determination to sustain this pressure over time.

The effectiveness of sanctions is debated — Russia has partially adapted its economy to this reality. But adaptation has a cost. Import substitution, the pivot toward less reliable and less technologically advanced partners, the rerouting of energy exports toward less profitable markets — all of this represents a real degradation of Russia's economic position. This degradation will not provoke the collapse of the Putin regime in the short term. It nonetheless contributes, over time, to the strategic exhaustion of the Russian war machine.

Conclusion: Zelensky has drawn a line — Lukashenko will have to choose

What the June 25 declaration changed

By publicly naming the five Belarusian military construction axes, by citing Russian documents that place Belarus within the framework of the STO, and by revealing the 500 mapped targets, Zelensky has changed the terms of the debate on the Belarusian threat. This is no longer analytical speculation about Lukashenko's intentions — it is documented fact and a clearly stated Ukrainian posture. Ukraine sees. Ukraine knows. And Ukraine has options.

This declaration places Lukashenko in an uncomfortable position: he can no longer claim that his border construction is innocuous, he can no longer deny being integrated into Russian STO military planning, and he knows that Ukraine has the capability to strike the 500 identified targets if it chooses to. That is the definition of a strategic ultimatum — formulated not with thundering threats, but with precise facts and a clear posture.

Lukashenko's future may be decided in Ankara

The NATO summit in Ankara, scheduled for July 7–8, could mark a turning point. If NATO sends sufficiently strong signals about the consequences of Belarusian entry into the war — credible signals backed by concrete reinforcements on the eastern flank — the combined Ukrainian and Western deterrence may be sufficient to maintain the status quo. Lukashenko has survived thirty years by playing on contradictions between his partners. The clarity of the message sent from Ankara will determine whether he can keep playing that game — or not.
