TESTIMONY: Zelensky at the European Council — when Ukraine forces Europe to choose sides

A summit that quietly changed everything

On June 18, 2026, the European Council convened in Brussels under particularly tense circumstances. President Volodymyr Zelensky attended in person, accompanied by his diplomatic team, to plead Ukraine's case before the twenty-seven leaders of the European Union. The official agenda: enlargement, renewed sanctions against Russia, and Ukrainian accession negotiations. But behind closed doors, a more explosive question was circulating: had European Council President António Costa overstepped his mandate by initiating contacts with Moscow?

According to European diplomatic sources, Costa's chief of staff, Pedro Lourtie, had held phone exchanges with a senior Russian official in the weeks preceding the summit — described officially as "brief contacts to open communication channels." This revelation fractured the summit between states that considered any dialogue with Moscow legitimate and those — including the Baltic states and Poland — who saw it as a betrayal of principles upheld since 2022.

António Costa opened a line to Moscow. Whatever his justification — exploring peace channels, maintaining minimal communication — this is a decision that belongs to the member states, not to the Council presidency. This confusion of mandates worries me as much as the contact itself.

Discreet calls that became a diplomatic bomb

Details of the contacts between Pedro Lourtie and the Russian official filtered gradually into the European press in the days preceding the summit. The official framing — "brief contacts to open communication channels" — failed to calm the critics. Several EU member states demanded explanations from Costa on the precise nature of these exchanges, their frequency, and above all their real purpose. Institutional transparency demands that the Council president account for such initiatives.

What particularly irritated Ukraine's firmest allies — Poland, the Baltic states, Finland, Sweden — was the timing. At the very moment when Zelensky sought to consolidate European support and secure a sanctions renewal for twelve months rather than six, the revelation of unauthorized contacts with Moscow weakened the EU's collective position. A message of disunity is exactly what Putin hopes to extract from every European summit.

National reactions: between caution and outrage

Member state reactions varied according to their geographic and historical proximity to Russia. Countries of Central and Eastern Europe, directly exposed to the Russian threat, reacted most forcefully. For them, opening contacts with Moscow without an explicit mandate from the member states amounts to normalizing dialogue with a state that is committing documented war crimes in Ukraine. Western European countries were more measured, with some seeing the communication channels as pragmatic caution.

The line between "maintaining channels" and "validating the interlocutor" is thin and politically explosive. Every contact with Moscow, even presented as purely technical, signals that dialogue is possible before Russia has met the conditions laid down — troop withdrawal, cessation of bombardments, release of prisoners. And that, for Kyiv, is unacceptable.

I understand the logic of "communication channels." In classical diplomacy, you always talk to the enemy. But we are not in classical diplomacy. We are in a conflict where Russia bombs hospitals while its diplomats smile in Brussels. Context changes everything.

Ukrainian presence as a political signal

Zelensky's participation in the June 2026 European Council was not merely symbolic. It embodied the Ukrainian claim to an active role in decisions that directly affect it. Ukraine has officially opened its EU accession negotiations — a historic milestone — and Zelensky insisted that this process be accelerated, not diluted into the standard candidacy procedures.

In his interventions at the summit, Zelensky hammered a consistent message: Europe must play a more active role in resolving the conflict, and not simply react to American initiatives or wait for Washington to impose a peace agenda. His physical presence in Brussels, face to face with the twenty-seven, was itself a political act: refusing to be reduced to a file discussed in his absence.

The twelve-month sanctions renewal: a Ukrainian victory

One of the concrete results of the June 2026 summit for Ukraine is the renewal of European sanctions against Russia for a period of twelve months, rather than the usual six. This change may appear technical, but it is strategically important: it reduces the frequency of renewal votes, diminishing the opportunities for recalcitrant member states to block or weaken the sanctions regime.

For Kyiv, this is a clear diplomatic victory. It means that Russia's trading partners — in Asia, in the Middle East — know that European sanctions are there to stay, reinforcing economic deterrence. And it demonstrates that, despite Costa's controversial contacts with Moscow, the EU's fundamental political line is holding.

Twelve months instead of six. Not spectacular, but concrete. In a world where every renewal vote is an opportunity for Budapest or Bratislava to apply pressure, reducing the frequency of those votes protects the coherence of European policy. Zelensky played that well.

Ukrainian conditions for any negotiation

Zelensky reiterated at the summit the Ukrainian conditions for any negotiation process with Russia: full withdrawal of Russian forces from internationally recognized Ukrainian territories, security guarantees for Ukraine from the West, and accountability mechanisms for war crimes. These conditions are not negotiable starting points — they are the minimum requirements for any peace that is not a capitulation.

Yet the contacts initiated by Pedro Lourtie — however limited their scope — included no reference to these conditions. Opening "communication channels" without a preset agenda amounts to validating Moscow as a legitimate interlocutor before securing even the slightest concession. For Zelensky, that is precisely the trap to avoid: every premature dialogue legitimizes the aggressor and weakens the allies' position.

The Russian position: time as a weapon

Russia did not publicly confirm the contacts with Lourtie, but American sources cited by US News noted in June 2026 that "Washington had not followed through on commitments stemming from Trump-Putin discussions." This formulation reveals that Moscow is playing on multiple boards simultaneously: engaging Washington in informal discussions, accepting Brussels' overtures, all while continuing military operations in Ukraine. Diplomacy is an additional weapon — not an alternative to war.

For Putin, every month of dialogue without a ceasefire is a month during which his forces advance or consolidate their positions. Every contact with a European official is a crack in the Western unity facade he seeks to widen. Understanding this is not cynicism — it is reading Russian strategy as it has expressed itself since 2014.

Putin uses diplomacy as a weapon. Every contact with a Western official is a narrative victory for Moscow — proof that the West is "looking for a way out." That is not true, but it is what Russian propaganda will make of it. And that, Costa should have anticipated.

Negotiations opened: a historic step

One of the most significant developments of the June 2026 summit is the official opening of Ukraine's accession negotiations with the European Union. This is a historic milestone for a country that has been fighting for its existence for more than four years. The Ukrainian candidacy, accelerated by the war and the political support of the majority of member states, has crossed a major institutional threshold.

But opening negotiations does not mean imminent accession. The standard accession process can take years, even decades. Entire chapters on the rule of law, corruption, and economic reforms must be negotiated and validated. For Ukraine, at war, this process means simultaneously reforming its institutions while managing a major armed conflict — a challenge without precedent in the history of European enlargement.

What eventual membership means for Ukrainian security

EU membership is not equivalent to NATO membership — it does not include a collective defense guarantee under Article 5. But it does mean integration into an economic, legal, and political space that makes any future Russian aggression economically and diplomatically prohibitive. It also means massive investments in reconstruction, access to structural funds, and reinforced institutional credibility.

For Zelensky, the opening of negotiations is a domestic political victory as much as an external one. It sends a powerful message to the Ukrainian population: the country's direction is clear, its future is anchored in the West, and the sacrifices made since 2022 have a horizon. In a country at war, this kind of political signal matters as much as weapons deliveries.

Ukraine opened EU accession negotiations while fighting for its survival. That is one of the most courageous political acts I have seen in contemporary diplomacy. Building the future under bombs — that takes a vision few leaders possess.

Europe cannot be a spectator of its own security

Zelensky insisted on a point many European leaders prefer to avoid: Europe must be an actor in resolving the conflict, not simply a financier of the Ukrainian war effort. This means clear political positions, credible mediation capacity, and above all the willingness to set conditions on any negotiation process — not simply react to initiatives from Washington or Moscow.

This demand is both legitimate and difficult to satisfy. The European Union is not a unitary actor in foreign policy — it is a coalition of twenty-seven states with diverging interests, histories, and threat perceptions. The courageous positions of Poland, the Baltic states, and Finland coexist with the hesitancy of Hungary, the nuances of Germany, and the electoral calculations of many governments. This is the institutional reality of the EU — and Zelensky knows it perfectly.

The Costa presidency: record and limits

António Costa had taken office with the stated ambition of strengthening the geopolitical voice of the European Union. His initiative to establish contacts with Moscow fits within that logic — wanting Europe to have its own channels, independent of Washington. The intention is not in itself illegitimate. The method — without an explicit mandate, without transparency with the most directly concerned member states — is far more questionable.

The political lesson is classic: in crisis diplomacy, the legitimacy of the process matters as much as the intention behind the acts. Costa may have wanted to do something useful. He did something of contested legitimacy. In a context of war and mutual distrust, form matters as much as substance — and the EU will pay the price for this mandate confusion at the next cohesion test.

I do not think Costa is pro-Russian. I think he is a Council president who wanted to play a geopolitical role for which his mandate is not sufficiently defined. That is an institutional problem as much as a political one. The EU must clarify who speaks on its behalf when it comes to Moscow.

A Union that holds, but under strain

Despite the controversy around Costa's contacts, the June 2026 European Council produced concrete results: twelve-month sanctions renewal, opening of Ukrainian accession negotiations, and confirmation of financial support for Ukraine. These results show that despite internal tensions, the European Union maintains functional cohesion on Ukrainian issues — even if that cohesion is sometimes laborious to achieve.

This is an important signal for Putin: contrary to his hopes, Europe has not fragmented on the Ukrainian question. Four years after the start of the full-scale invasion, European support holds — imperfect, contested, sometimes painfully obtained, but real and concrete. Russia had bet on rapid European fatigue. It was wrong.

The coming months: a permanent test

The coming months will be decisive for European cohesion on Ukraine. Legislative elections in several member states, tensions over defense budgets, migration, inflation — all of these factors will create pressure on governments that must justify the cost of Ukrainian support before weary electorates. It is in this context that Costa's contacts with Moscow are most dangerous: not because they change policy immediately, but because they feed the Russian narrative that "Europe is looking for an exit."

This narrative must be countered with clear acts, not merely declarations. Every sanction upheld, every billion disbursed, every accession negotiation advanced — these are the effective counter-narratives. And Zelensky, by demanding more of Europe and less diplomatic ambiguity, is pushing in the right direction.

Europe holds. Not brilliantly, not without contradictions, not without moments of hesitation that hurt. But it holds. And in today's world, holding — continuing to aid, to sanction, to build the future with Ukraine — is already a form of victory over Putin.

The European choice renews itself every day

The June 2026 European Council confirmed that Europe is not abandoning Ukraine. Sanctions renewed, accession underway, financial support maintained: the concrete indicators of European engagement are there. But it would be naive to believe this choice is definitively secured. It renews itself at every summit, every vote, every budgetary decision. European cohesion is not a stable state — it is a permanent effort.

Zelensky as a mirror of European ambition

What Zelensky reveals to Europeans, looking them in the eye in Brussels, is their own ambition — or its absence. He asks a simple question: are you prepared to defend the values you proclaim? Every time Europe answers yes in concrete terms — sanctions, accession, military aid — it also answers its own question about what it is. And for now, despite Costa's contacts and internal tensions, the answer remains, laboriously but genuinely, yes.

Zelensky at the European Council is a mirror held up to Europe. And what that mirror shows is a Union that hesitates sometimes, contradicts itself sometimes, but still refuses to submit to Putin's narrative. For me, that is enough to maintain hope — fragile, but real.

Acts, not just declarations

The June 2026 summit delivered concrete acts: twelve months of sanctions, opening of accession negotiations. But the Costa-Lourtie-Moscow controversy was a reminder that European cohesion on Ukraine is never guaranteed. It requires institutional discipline, transparency among member states, and the will to resist Russian attempts to fragment the Alliance. These requirements will not disappear with the end of the war — they will define the European security architecture for the decades ahead.

What Ukraine expects from Europe

Ukraine does not expect perfection from its European allies. It expects consistency. Consistency in financial and military support. Consistency in sanctions. Consistency in the accession perspective. And consistency in refusing to validate Moscow as a legitimate interlocutor without preconditions. Zelensky came to Brussels not to give thanks — but to remind them that this consistency is what Ukraine is buying with the blood of its soldiers. And that price deserves better than informal, unmandated contacts with the enemy.

Zelensky's trust in Europe is not unconditional — and it should not be. It is earned summit by summit, sanction by sanction, billion by billion. And every time Europe rises to the occasion, something fundamental in the world order is preserved. That is why this summit mattered.
