The Druzhba Deal Shows EU Solidarity Is Transactional — And Getting More Expensive

On April 22, Russian oil began pumping through the Druzhba pipeline again. Within hours, EU ambassadors in Brussels approved a €90 billion loan for Ukraine¹. The sequencing was not subtle. Viktor Orbán, in his final weeks as Hungary's prime minister after a crushing election defeat on April 12², had made the terms explicit for months: "no oil, no loan." Ukraine repaired the pipeline segment damaged by a Russian drone strike in January. Brussels facilitated the fix. Oil flowed. The veto lifted. The 20th sanctions package against Russia was approved alongside it.

This is a success, in the narrow sense. Ukraine gets critical liquidity for 2026 and 2027. But I think it is important to be honest about what the mechanism reveals, because the pattern playing out across EU decision-making on Ukraine has become unmistakable — and it is getting worse, not better.

Start with the basic structure. What happened this week was a quid pro quo in which the continued flow of sanctions-exempt Russian oil to Hungary and Slovakia was the explicit price of allowing EU financial support for Ukraine to proceed. The Druzhba pipeline carries Russian crude to MOL refineries in Hungary and Slovakia under an exemption from EU sanctions that has no defined end date³, according to energy analysis firm Kpler. That exemption was first granted in May 2022 when the EU needed unanimity for its sixth sanctions package. What was framed as a temporary accommodation for landlocked states has become permanent architecture. Hungary has used it as leverage in every major EU decision on Ukraine since.

Now, there is a defensible case for pragmatism here. The EU operates under unanimity rules for foreign policy and sanctions. You cannot wish away the veto; you can only negotiate around it. And the outcomes, taken in isolation, have been real. Ukraine received the €50 billion facility in 2024. Seventeen, then eighteen, then twenty rounds of sanctions were adopted. The coalition formally held 27 members. If the alternative to striking a deal was permanent paralysis on Ukraine funding, then the deal was worth striking. I take that argument seriously.

But the argument for pragmatism has a critical assumption baked in: that the costs of accommodation are bounded. And the evidence from the last two years suggests they are not.

Let me walk through the sequence. In December 2023, the European Commission released €10.2 billion in previously frozen cohesion funds⁴ to Hungary, timed to the European Council summit where Orbán's veto on Ukraine funding was the central obstacle. The Commission's official position was that Hungary had met judicial reform conditions. But civil society organizations evaluating the reforms called them "makeshift solutions"⁴ that failed to resolve long-standing concerns. A peer-reviewed study in the Journal of European Public Policy found that Hungary's compliance was a "rational cost-benefit calculation" — the government selectively met conditions where funds were at stake and ignored the rest⁵. The European Parliament criticized the funds release as "untransparent" and "political."

That was iteration one. Now look at what followed.

In July 2025, Slovak Prime Minister Robert Fico blocked the 18th sanctions package for over six weeks. His opposition had nothing to do with the sanctions themselves⁶. He was using the unanimity requirement on sanctions to extract leverage on the separate EU plan to phase out Russian fossil fuels by 2028 — a plan subject to qualified majority voting, which he couldn't block directly. As Euronews reported⁶, "Bratislava resorted to sanctions, which require unanimity, to extract concessions from Brussels." Fico lifted his veto after receiving a "comfort letter" from Commission President von der Leyen⁷ promising emergency exemption procedures if Slovakia faced supply crises. The letter contained, by multiple accounts, no concrete financial commitments. EUobserver noted⁸ it recalled a previous "useless face-saving declaration" granted to Hungary.

Fico then vetoed the 19th sanctions package in October 2025, conditioning approval on EU attention to the automotive industry and energy prices⁷. He lifted that veto after EU summit conclusions were revised to include language on his concerns. In December 2025, he and Orbán tried to block the €210 billion Russian asset freeze⁹ — and the EU responded by invoking an emergency treaty rule to bypass their vetoes entirely, a move Orbán called the end of the rule of law in Europe.

This is the pattern I want to highlight. It is not a static picture. Each iteration involves higher stakes, more creative obstruction, and an EU that oscillates between accommodation and procedural workarounds — neither of which resolves the underlying incentive structure.

The strongest counterargument is that the costs, while real, have been manageable. Ukraine got its money every time. Sanctions held. And with Orbán now defeated — Péter Magyar's pro-European Tisza party won a two-thirds supermajority² — the most egregious actor in this dynamic is leaving the stage. PIIE analysis notes¹⁰ that Magyar's incoming government is set to receive up to €17 billion in previously frozen funds in exchange for genuine rule-of-law reforms, and Chatham House observes¹¹ that Budapest will become "less useful to Moscow as an internal point of leverage."

That is all true. Orbán's defeat is genuinely important. But I think it actually proves the structural point rather than refuting it. Consider: it took a domestic electoral revolution to remove the veto problem from the Hungarian side. The EU's own institutional mechanisms did not remove it. €17 billion in funds remain frozen as of March 2026¹² — not because conditionality worked as designed, but because Hungary under Orbán chose to sacrifice the money rather than comply on politically sensitive reforms involving LGBTQ+ rights, asylum policy, and academic freedom. Conditionality successfully pressured the areas where Orbán calculated the cost-benefit ratio favored compliance. On everything else, it was ignored for years.

And Fico remains. He has not been voted out. His veto playbook⁷ is now well-documented: use unanimity requirements on one file to extract leverage on a completely different file. He vetoed sanctions to get energy concessions. He vetoed loans to get pipeline guarantees. Slovakia's strategy, as a Bratislava Policy Institute analyst described it to Balkan Insight¹³, "aligns with well-documented patterns of member states aimed at extracting financial, regulatory and political rents."

The revenue numbers matter too. According to CREA's monthly tracking¹⁴, Hungary purchased €393 million worth of Russian fossil fuels in September 2025 alone, including €166 million in crude oil via the Druzhba exemption. Slovakia added another €207 million. The Druzhba exemption is not a rounding error in the sanctions architecture — it is a permanent revenue channel for Moscow, preserved because the political cost of closing it exceeds the political cost of leaving it open.

Where does this leave us? Magyar's victory changes the Hungarian variable substantially. But the institutional vulnerability — unanimity requirements that convert veto power into a bargaining chip — remains intact. Fico is still operating the playbook. Belgium has raised concerns about the frozen Russian assets on different grounds. The next contentious vote on Ukraine will encounter the same structural dynamics, minus Orbán but plus whoever calculates that obstruction pays.

The thing to watch is whether Magyar's new government actually unlocks the remaining €17 billion by meeting the August 2026 deadline on recovery fund milestones — and whether the EU treats that process as genuine conditionality or as another political accommodation timed to a convenient political moment. If the funds flow before meaningful reforms are verified, it will confirm that EU money follows political alignment more than institutional compliance. If the EU holds the line and Magyar delivers real reforms first, it would be the single strongest piece of evidence that the conditionality mechanism actually works when a willing partner is on the other side. That distinction will tell us whether what we have been watching is transactional diplomacy within functioning institutions, or an institution whose functioning depends on transactions.
