NARRATIVE: "With Bandera, Ukraine will not enter the EU" — the Polish challenge

June 30, 2026 — a sentence that lands like a bomb

On June 30, 2026, Polish Deputy Prime Minister and Defense Minister Władysław Kosiniak-Kamysz spoke a sentence on Polsat News that traveled through European chancelleries like an electric charge: "In the EU, you cannot place on a pedestal those who undermine European cooperation. With Bandera, Ukraine will not enter the European Union." This was not a diplomatic formality. It was an ultimatum, publicly delivered, during a war.

The context is a crisis in Polish-Ukrainian relations that has intensified since Ukraine named a military unit in honor of the Heroes of the UPA — the Ukrainian Insurgent Army. On June 19, 2026, Polish President Karol Nawrocki had already stripped Zelensky of the Order of the White Eagle, one of Poland's highest distinctions. Kosiniak-Kamysz's statement on Bandera is an extension of that gesture — a message simultaneously to Kyiv, to Brussels, and to the Polish public.

Who was Stepan Bandera and why his name divides

Stepan Bandera was the founder of the radical wing of the Organization of Ukrainian Nationalists (OUN-B). In Ukraine, he is commemorated primarily as a resistance fighter against Soviet occupation. In Poland, his name is inseparable from the events of 1943-1945 in Volhynia, where members of the UPA killed thousands of Poles. Both national memories are real and painful — they have coexisted for decades without resolution.

What is new in 2026 is the instrumentalization of this memorial dispute in the context of a total war and an EU accession process. What Kosiniak-Kamysz is doing — citing Bandera as a condition for Ukrainian accession — is transforming a legitimate historical debate into a foreign policy lever with immediate consequences for the lives of millions of Ukrainians.

I do not deny Polish pain over Volhynia. That pain is real, documented, and deserves respectful treatment in any serious historical dialogue. What I contest is the use of that pain as a diplomatic weapon against a country currently fighting for its survival. There is a time for memory and a time for solidarity. In 2026, both are necessary — but in that order.

The National Pantheon bill

On June 28, 2026, on the occasion of Ukraine's Constitution Day, President Volodymyr Zelensky submitted to Parliament a bill creating a Ukrainian National Pantheon to honor distinguished Ukrainians. This gesture is simultaneously a response to Polish pressure and an assertion of cultural sovereignty.

His formulation left no room for ambiguity: "No one will ever dictate to us how to live, how to speak, who to love, who our heroes are." This declaration was received in Warsaw as a direct challenge. It was also a response to Polish opposition leader Jarosław Kaczyński, who had called on Poland to block any new round of Ukrainian EU accession negotiations — taking an even harder line than the Tusk-Kosiniak-Kamysz government.

Ukraine's logic: the cost of renunciation

To understand why Ukraine does not yield on the Bandera question, one must understand Ukrainian internal dynamics. In a country fighting for its national identity since the 2022 Russian invasion — and since the 2014 invasion before it — historical memory is not an academic abstraction. It is a living part of national identity, tied to resistance against all forms of occupation, Soviet and Russian alike.

Yielding on Bandera under Polish pressure would be interpreted by a significant portion of Ukrainian society as a symbolic capitulation to an ally using accession leverage to impose its vision of history. This interpretation, right or wrong, has real political effects. Zelensky governs a country at war, with a public that accepts immense sacrifice — and whose tolerance for external pressure on identity questions is well understood.

I understand Zelensky's position. Yielding on national symbols under an ally's pressure, during a war for national survival, would be politically devastating in Ukraine. But I also understand the Polish position. The art of leadership in this context would be to find a formula that acknowledges both memories without one crushing the other. That formula has not yet been found.

What historians say and what politicians have not yet done

Polish and Ukrainian historians have worked for decades on the events of Volhynia and the legacy of the UPA. This academic work is serious, rigorous, and often painful for both sides. Bilateral commissions have been formed, documents have been studied, testimonies collected. This work deserves to be continued, deepened, and supported by both governments — independent of the diplomatic pressures of the moment.

What is missing is the political will to translate academic conclusions into official gestures of reconciliation. Poland and Ukraine have not yet found an equivalent of Brandt's Warsaw kneeling in 1970, or the postwar Franco-German declarations. These models of reconciliation exist in European history. They show it is possible to honor victims on both sides without canceling either nation's memory.

Reconciliation as a condition for accession: a reversed logic

What Kosiniak-Kamysz proposes — conditioning EU accession on the resolution of the memorial dispute — is a reversed logic. Previous EU enlargements did not wait for all historical disputes between neighboring countries to be resolved. Poland itself has been an EU member since 2004 despite its own unresolved historical tensions with Germany, the Czech Republic and other neighbors.

Historical reconciliation is a long-term process that happens better within a shared political community than while waiting anxiously outside. It is precisely within European institutions — where member states sit together, cooperate, and confront each other in regulated frameworks — that historical disputes most often find paths to gradual resolution. Conditioning Ukrainian accession on the prior resolution of this dispute inverts the causal order of European history.

The Franco-German reconciliation model was built within the European framework, not before it. The shared political community was the place of reconciliation, not its precondition. That is the lesson Poland seems to have forgotten in its relationship with Ukraine. Ukrainian accession could be the occasion for deeper historical dialogue — if we approach it as a process, not a verdict.

When two countries slow Ukrainian accession simultaneously

While Poland brandishes its memorial veto, Péter Magyar's Hungary continues to block the opening of the five remaining accession clusters. This combination of simultaneous brakes — Hungarian and Polish — creates considerable pressure on the timeline of Ukrainian integration. The European Commission, which had hoped to open all clusters in 2026, must scale back its ambitions.

The fundamental difference between the two blockades is their nature. The Hungarian blockade is institutional and tied to conditionality clauses — it can be progressively lifted through documented political concessions and compromises. The potential Polish blockade is memorial and identity-based — it touches Ukraine's cultural sovereignty in a way Kyiv cannot easily satisfy without complex internal political decisions.

The EU facing a governance crisis in enlargement

This situation illustrates a structural weakness in the European enlargement process: the absence of a mechanism to manage historical disputes between a candidate state and a member state. The chapters of the acquis communautaire cover dozens of technical domains — environment, competition, agriculture, social rights. But they do not cover historical memory, commemorative policies or bilateral relations between neighbors.

This institutional gap gives member states like Poland the ability to block an accession process for reasons not formally covered by accession criteria. Brussels has no tool to adjudicate between Ukrainian and Polish national memory. This is a gap that European institutions will need to fill — with or without the Ukrainian crisis as a catalyst.

There is a tragic absurdity in the fact that Ukraine — which is fighting a Russian invasion with weapons that Poland supplied — faces a potential veto on its European accession by that same Polish ally, for reasons of memorial politics. This is not a criticism of Poland — it is an observation about a European system lacking tools to manage these tensions.

The cluster delay and its economic effects

Every month of delay in opening Ukrainian accession clusters has concrete, measurable economic consequences. International investors — sovereign funds, multinationals, reconstruction companies — need a stable and predictable legal framework to commit capital in Ukraine. The certainty of EU membership is one of the most important guarantees of that stability.

The Ukraine Recovery Conference held in Gdańsk in June 2026 highlighted the enormous reconstruction needs — hundreds of billions of euros of investment over ten to twenty years. These investments will not flow optimally without the EU accession perspective. Every negative signal from Budapest or Warsaw is a negative signal for private investors still hesitating to commit.

The message to Ukrainian refugees in Europe

Accession blockades also carry an immediate human dimension. Millions of Ukrainian refugees currently live in European countries. Many are women with children, whose husbands and sons are at the front. Their decision to return to Ukraine after the war depends largely on their perception of the country's future — and therefore on its European trajectory.

An accession process advancing slowly, conditioned on the resolution of complex historical disputes, sends an ambiguous signal to these refugees: your country is perhaps on the road to Europe, but this road is still long and dotted with political obstacles. This signal can influence return decisions, diaspora mobilization for reconstruction, and even Ukraine's postwar demographic recovery. Diplomatic blockades have human effects that statistics do not always capture.

I think of the millions of Ukrainian women who are refugees in Poland, Germany, France. They have often been generously welcomed by their host countries — and especially by Poland. These women deserve that the governments that welcomed them work with Kyiv to find a path of historical reconciliation — not to block their European future with ultimatums.

Poland, a crucial ally whose demands complicate the picture

Poland remains one of Ukraine's most important allies. It has supplied weapons, welcomed millions of refugees, kept its borders open, devoted 4.48% of its GDP to defense, and was the first nation to deliver fighter jets to Kyiv. This record is exceptional and deserves sincere recognition. But it does not place Poland beyond critical scrutiny of its diplomatic methods — especially when those methods risk harming the European integration of a country it claims to support.

Kosiniak-Kamysz may be right on the substance: Ukraine must resolve its historical disputes with its neighbors to be a credible and stable EU member. But the form — a public, televised ultimatum, delivered in the middle of a war — is counterproductive. It hardens positions, complicates Zelensky's task on his domestic public opinion, and offers Putin a propaganda window he should not have been given.

War, alliances and the cost of diplomatic clumsiness

There is something deeply troubling about the fact that Ukraine's greatest diplomatic difficulties in June 2026 come from its direct allies — Poland on the memorial question, Hungary on accession clusters. Russia, for its part, takes no diplomatic pause to express its dissatisfactions. It bombs. It advances. It exploits every crack in Ukraine's support coalition to reinforce its narrative: the West is unreliable, European promises are empty, Ukraine is alone.

This narrative is false in its premises — Western aid to Ukraine is real and substantial. But it is fed by episodes like the Polish-Ukrainian standoff over Bandera. These are the visible fissures, captured in international media, that Moscow uses to demoralize Ukrainians and reassure its own partisans. Ukraine's allies have a responsibility to understand this — and to adapt their diplomatic methods accordingly.

I am not saying Poland should silence its historical claims. They are legitimate. I am saying that alliance diplomacy in wartime requires awareness of the effects of every public statement. Kosiniak-Kamysz may have gained a few points in Polish polling. He may have damaged the cohesion of the pro-Ukraine coalition. That calculation deserves to be revisited.

Societies that are evolving on the memorial question

Beyond government positions, it is important to note that Polish and Ukrainian societies themselves are evolving on memorial questions. Studies show that younger generations in both countries — those who grew up after the fall of communism, who travel freely in Europe, who have friends in both countries — have a more nuanced relationship with the historical traumas of their elders. This generational shift is a resource for long-term reconciliation.

In 2022, when Russia launched its full-scale invasion, solidarity between Poles and Ukrainians was remarkable. Millions of Ukrainian refugees were welcomed into Polish homes with extraordinary generosity. This civil solidarity transcends official political disputes. It shows that, on a human level, reconciliation is possible — and that it is, to some degree, already happening.

The risk of a generational fracture in both countries

The risk posed by Kosiniak-Kamysz's Bandera statements is to revive divisions that, without this political instrumentalization, might have been naturally diminishing. When a minister wields a contested historical symbol as a public diplomatic weapon, he awakens passions that the patient work of historians and civic organizations was trying to transform into mutual understanding.

For young Ukrainians who grew up seeing Bandera as a resistance fighter against Soviet occupation, the Polish ultimatum looks like an attempt to impose a foreign vision of their own history. For young Poles who grew up with the memory of Volhynia, Ukraine's refusal to distance itself from Bandera seems disrespectful to their ancestors' victims. Both perceptions are humanly understandable — and politically explosive if not carefully managed.

Polish-Ukrainian reconciliation is one of the most important — and least covered — projects of contemporary European politics. It is being built in classrooms, universities, civic associations, and families hosting refugees. Television statements by ministers can undo in seconds what these actors build patiently. That is why the words of leaders matter.

The Ukrainian minority in Poland and the Polish minority in Ukraine

There is a significant Ukrainian community in Poland, vastly enlarged by war refugees since 2022. And there are, in Ukraine — notably in Galicia and Volhynia — historical Polish communities whose situation has evolved since Ukrainian independence. These minority communities can function either as bridges — vectors of mutual understanding, shared culture, concrete human relationships — or as fractures, if their respective governments use them as pressure levers.

Transcarpathia, with its Hungarian minority, is the most visible example of this phenomenon in the current context. But Polish minorities in Ukraine and Ukrainian minorities in Poland are also potential resources for reconciliation — provided that politicians do not instrumentalize them as pretexts for ultimatums. The cultural associations working on both sides of the border deserve official support, not political manipulation.

The diplomacy of historians: a model to activate

The Franco-German textbook commission, created after World War II, is a model of what the diplomacy of historians can achieve. It enabled both countries to teach a shared history of their conflicts — not an identical history, but one that acknowledges perspectives from both sides. A similar model for Poland and Ukraine would allow the UPA and Bandera question to be addressed within a rigorous academic framework, far from electoral pressures and televised ultimatums.

This proposal is not naive — it has been advanced by historians and civic organizations in both countries for years. What it has lacked is the political will to implement it with the necessary resources. The context of 2026 — however painful — could be an opportunity to give this work the institutional framework and funding it deserves. Ukraine's EU accession would be the perfect occasion to create such a commission under European auspices.

The Polish-Ukrainian commission of historians exists partially. It lacks resources, visibility and political support. Giving it the means to do real work would be infinitely more useful than televised statements about Bandera. I hope for that. But in the meantime, bombs fall, clusters are blocked, and History waits for politicians to catch up with historians.

Two peoples, two memories, one common destiny

The history of Poland and Ukraine is that of two peoples who have shared centuries of coexistence, tensions, cooperation and shared tragedies. The dispute over Bandera and the UPA is only one chapter — painful, real, unresolved — of a longer, more complex relationship. Resolving it requires time, political will and institutions: a permanent bilateral commission of historians, reciprocal symbolic gestures, dialogue spaces.

What Europe can do

The EU — whose two countries both aspire to solid membership, one current, one future — has a role to play as a mediator and institutional framework for reconciliation. It can encourage the creation of a bilateral Polish-Ukrainian commission on memorial questions. It can offer funding for shared historical research. It can, above all, refuse to let this dispute block indefinitely an accession process that is in the interest of all of Europe. The narrative of this reconciliation has not yet been written — and it may be one of the most important tasks of European policy in the years ahead.

This narrative ends without a happy ending, because there is not one yet. The standoff between Warsaw and Kyiv over Bandera continues. Accession clusters are partially blocked. Ukraine still fights. But I hold onto this: Poland and Ukraine share a common enemy — Russia — and a common future — Europe. These two truths are larger than Bandera. Sooner or later, politicians will have to act on them.
