OPEN LETTER: What Germany's Nord Stream Charges Owe Us

Introduction: A letter to those who will exploit this case against Ukraine

A court case, not a geopolitical verdict

On July 2, 2026, German prosecutors formally charged a Ukrainian national with taking part in the sabotage of the Nord Stream pipeline in 2022, alleging he acted "on behalf of Ukrainian state entities." That phrase, tucked into a technical indictment filed before a regional court in Hamburg, immediately took on a political weight German justice had probably not fully anticipated. I am writing to you, readers who will follow this case in the weeks ahead, to draw a distinction that media haste risks erasing: an indictment is not a verdict, and a prosecutor's allegation, however detailed, is not proof established before a court.

The suspect, identified by the initials Serhii K. under German confidentiality rules, is a former officer of the Ukrainian army. He had already been arrested in Italy in the summer of 2025 and extradited to Germany in November of that same year. He denies any involvement in the explosions that destroyed three of the four undersea pipelines linking Russia to Germany via the Baltic Sea. At this stage, the court case remains an accusation to be tried, not a definitive conclusion about the Ukrainian state's political responsibility.

Why this case deserves to be handled with rigor

This case is being closely tracked by Beijing and Moscow, two capitals that have never hidden their interest in feeding an anti-Western narrative in which Ukraine, rather than Russia, would bear responsibility for sabotaging a major energy infrastructure. Precisely for that reason, factual rigor matters more than ever. Taking this accusation seriously does not mean accepting it blindly; it means examining it with the same standard of proof as any other court case, without yielding either to reflexive dismissal or to eager exploitation.

That is the point of this open letter: to remind readers that solidarity with Ukraine in its war of survival against the Russian invasion does not require closing our eyes to serious allegations brought by an independent judicial system, that of an allied country, Germany. On the contrary, it requires demanding the truth, whatever it turns out to be, and refusing to let this case be weaponized, in either direction.

Some will ask why I'm devoting an open letter to a subject that could tarnish Ukraine's image. My answer is simple: supporting a country at war does not mean granting it absolute moral immunity. It means demanding the truth with the same rigor we would demand of any other actor, precisely because the Ukrainian cause deserves to be defended with solid arguments, not denial.

What the German charges actually say

An operation meticulously documented by prosecutors

According to the indictment detailed by German federal prosecutors, Serhii K. allegedly led a team made up of several professional divers, a skipper, and an explosives expert. The group is said to have chartered a yacht from the German port of Rostock, on the Baltic, using forged identity documents. The suspect reportedly entered Germany from Poland using a forged Ukrainian passport before joining his team on the German Baltic coast.

According to prosecutors, the team then transported significant quantities of military-grade explosives through international waters to an area near the Danish island of Bornholm, before attaching them to the pipelines and installing delayed-action detonators. The explosions occurred four days later, destroying three of the four lines of the Nord Stream 1 and Nord Stream 2 system, releasing record quantities of methane into the atmosphere. The charges against the suspect include an attack on civilian energy infrastructure, an act that could be classified as a war crime under international law.

The element that shifts the political stakes

What sets this July 2026 indictment apart from earlier stages of the investigation is prosecutors' explicit claim that the operation was "prepared and carried out with the full knowledge and consent of the Ukrainian government." This marks the first time a German public body has pointed this directly at the Ukrainian state itself, rather than at private actors or military personnel acting outside any official chain of command. This nuance, diplomatically enormous, deserves to be stated precisely rather than crudely summarized.

Ukrainian President Volodymyr Zelensky said he only received the full details of the indictment on the day it was published. Authorities in Kyiv said they did not have enough information to respond in detail to the German allegations. This cautious response, rather than an immediate categorical denial, illustrates the complexity of a case where the full truth remains, to this day, partly obscured.

The German case file is impressive in its detail. But being impressive isn't the same as proving something beyond reasonable doubt in court. It will take a trial, witnesses questioned under oath, a defense able to contest every element, before this case stops being a meticulously documented hypothesis and becomes an established judicial truth.

A chaotic legal saga since 2022

Twists that delayed the truth

The road to this July 2026 indictment has been long and bumpy. In August 2024, Germany had already issued an arrest warrant against another Ukrainian national, identified as Volodymyr Z., living near Warsaw. Poland received a European arrest warrant, but the suspect fled to Ukraine before Polish authorities could apprehend him. A court in Warsaw ultimately refused, in October 2025, to extradite another Ukrainian suspect detained in the meantime, ruling that Germany had provided only information too general to justify extradition.

The suspect at the center of the 2026 indictment, identified by several media outlets as Serhii Kuznietsov, followed a different legal path. Arrested in Italy in August 2025 while on vacation with his family, he was extradited to Germany after Italy's Supreme Court approved the extradition request in November 2025, despite an earlier Italian court ruling that had temporarily blocked the process. According to investigators, the suspect allegedly incriminated himself during intercepted phone calls with relatives while in detention in Italy.

What Germany's Federal Court had already suggested

It should be noted that in December 2025, Germany's Federal Court of Justice had already issued a ruling stating there was a "high degree of probability" that the pipeline explosions were carried out "on behalf of a foreign state," namely Ukraine. The July 2026 indictment thus fits within the logical continuity of this earlier judicial assessment, rather than as a sudden, unexpected break in German authorities' reasoning.

This judicial continuity strengthens the case's procedural credibility, without turning it into absolute certainty. German courts have, on several occasions over this nearly four-year investigation, changed legal classifications and refined their understanding of the responsibilities involved — a typical path for a complex investigation into a cross-border sabotage carried out at sea, far from any surveillance camera or easily identifiable direct witness.

I note, with some discomfort, that this investigation took nearly four years to produce its first formal charge against a specific individual. That delay isn't necessarily suspicious — cross-border underwater investigations are notoriously complex — but it shows just how much of an incomplete puzzle the full judicial truth about Nord Stream remains, even today.

What Zelensky knew, and what he never admitted

The private financing and chain-of-command theory

An article published by Der Spiegel in February 2026 had already claimed the operation was approved by former Ukrainian armed forces commander-in-chief Valerii Zaluzhny, but without the knowledge of President Volodymyr Zelensky, whose office was reportedly not informed at the time. The same report identified a private Ukrainian citizen as the operation's main financier, covering roughly $300,000 in operational costs. An article by the Wall Street Journal published in June 2026 repeated a similar theory, known as the Andromeda theory, detailing the use of a yacht to transport the explosives.

This distinction between a presidential decision and a military initiative carried out outside the official chain of command is precisely the crux of the current political debate. According to a DW News report from July 3, 2026, two schools of thought divide analysts: one holds that Zelensky knew of the sabotage plans before their execution in September 2022; the other, seen as better supported by some journalistic research, holds that he was not informed during the planning phase. This honestly documented uncertainty deserves to be preserved, rather than flattened in one direction or the other for rhetorical convenience.

Kyiv's constant denial over four years

Since 2022, the Ukrainian government has firmly denied any official state involvement in the pipeline sabotage. President Zelensky has repeatedly said Ukraine never ordered such an operation. His advisers, including Mykhailo Podoliak, even publicly suggested in 2024 that only Russia had, at the time, the technical and financial capabilities necessary to carry out an operation of this scale — an alternative theory German investigators have never taken as seriously as the Ukrainian lead.

This constant denial, maintained for nearly four years despite the gradual accumulation of technical evidence pointing toward Ukrainian actors, now places Kyiv in a delicate diplomatic position. Either the denial reflects sincere ignorance at the top of the state of an operation carried out by military elements acting autonomously; or it reflects a deliberate communications strategy aimed at preserving relations with Western allies, Germany chief among them, whose support remains indispensable to Ukraine's war effort.

There is a considerable moral and political difference between a state that orders a sabotage operation and patriotic servicemen who, amid the chaos of an unprovoked war, decide to act alone to weaken the war machine invading them. That distinction doesn't automatically absolve Ukraine, but it forbids treating this case as a simple act of state terrorism comparable to the crimes Russia commits daily on Ukrainian soil.

Beijing and Moscow, the real winners of this narrative

An anti-Western narrative ready to use

We must state plainly what this indictment offers Russian and Chinese propaganda: a ready-made story in which the West armed and supported a country capable of sabotaging critical energy infrastructure in the heart of Europe without directly assuming political responsibility. Russian Foreign Minister Sergei Lavrov had already claimed, even before the 2026 indictment, that the pipelines were destroyed by Ukrainian saboteurs with the apparent support of Western intelligence services, a claim nothing in official German investigations has ever corroborated.

Russian news agency TASS covered this indictment with telling eagerness, presenting it as the definitive confirmation of a thesis Moscow has pushed since 2022 to absolve itself of any responsibility for destroying its own gas export infrastructure. It is precisely this propaganda reflex, exploiting every legal nuance to build a simplified narrative against Ukraine and the West, that must be countered with factual rigor rather than reflexive denial.

China, an interested spectator of a potential Western rift

For Beijing, this case fits into a broader strategy of questioning the reliability and cohesion of Western democracies against authoritarian regimes. Every apparent crack between Germany and Ukraine, every doubt cast on Kyiv's moral conduct in its war against the Russian invasion, feeds a Chinese narrative that Western democracies are less virtuous than they claim, and therefore less entitled to criticize Beijing's practices in Taiwan, Xinjiang, or the South China Sea.

That is why this case cannot be treated as a simple bilateral legal matter between Germany and a Ukrainian individual. It fits into a broader information war in which every authoritarian regime — Russia, China, but also Iran and North Korea by ideological extension — seeks to exploit any Western moral ambiguity to legitimize its own aggression and repression.

It takes formidable clarity to navigate this case: acknowledging the German indictment deserves to be taken seriously without handing Moscow and Beijing the rhetorical gift they're hoping for. Judicial truth, once clearly established, must take precedence over the communications calculations of all sides, Ukrainian and Western alike.

Berlin and Kyiv, a relationship that shouldn't break

The weight of alliance against the weight of the case

According to analysts cited by DW News, German officials probably knew, as early as 2022-2023, that Ukrainian individuals were involved in the sabotage, without that knowledge significantly altering German policy of support for Ukraine since then. This observation, if confirmed, illustrates a form of political pragmatism: Germany chose to maintain its military and financial commitment to Kyiv despite longstanding suspicions, likely judging that Ukraine's survival against Russian aggression outweighed the diplomatic complications tied to this energy case.

This pragmatic Berlin approach deserves recognition, even as it now exposes the German government to greater internal political pressure, notably from opposition parties that could exploit this indictment to challenge the level of military and financial support granted to Ukraine. The upcoming trial before the Hamburg regional court will inevitably become as much a political battleground as a legal one.

What the West must demand of itself

My conviction remains that Western support for Ukraine must never hinge on the absolute moral perfection of every actor involved in its defense. Russia invaded a sovereign country without provocation, deliberately bombs civilian infrastructure, and continues a colonial war of aggression that has cost countless Ukrainian lives. No revelation about Nord Stream, even one fully confirming the involvement of Ukrainian military elements acting without explicit presidential order, rebalances this fundamental moral asymmetry between aggressor and victim.

But this conviction does not exclude the demand for transparency. Ukraine, if members of its armed forces indeed acted autonomously to destroy energy infrastructure partly belonging to Western interests, must own up to that reality with the same candor it rightly demands from the international community regarding documented Russian war crimes on its own soil.

Demanding truth from your allies isn't an act of betrayal. It's an act of trust. You don't protect a strategic friendship by avoiding hard subjects; you protect it by working through them together, honestly, even when the answer turns out to be uncomfortable.

The coming trial, the next step toward an incomplete truth

What Hamburg will need to establish

The Hamburg regional court, where Serhii K. is currently held in pretrial detention, will need to establish beyond reasonable doubt not only the suspect's material participation in the sabotage operation, but also the exact nature of his link to "Ukrainian state entities," a phrase that remains legally vague and politically explosive. The suspect's defense, which denies any involvement, will have the opportunity to contest every piece of technical and testimonial evidence gathered by prosecutors over nearly four years of investigation.

German Attorney General Jens Rommel described the evidence gathered against the suspect as "overwhelming," citing in particular material found on his cell phone and intercepted conversations during his detention in Italy, where he reportedly provided self-incriminating statements. But calling evidence overwhelming before an adversarial trial remains a piece of judicial communication that will have to be validated, or disproven, by the proceedings ahead.

What this trial will mean for the Kyiv-Berlin relationship

Whatever the final verdict, this trial will become a moment of truth for the relationship between Germany and Ukraine. A conviction confirming the involvement of Ukrainian state entities would force Kyiv into difficult public explanations, potentially damaging to its credibility with segments of German public opinion already divided over the level of support for Ukraine's war effort. An acquittal, conversely, would strengthen Ukraine's position but leave open the question of who actually orchestrated the operation.

Either way, there will be a need to resist the temptation to turn this complex legal case into an instant political weapon, in either direction. Judicial truth deserves time, rigor, and patience — three qualities that social media and state propaganda, Russian and Chinese alike, never show when exploiting a controversy to their advantage.

I prefer the discomfort of an incomplete truth to the false comfort of a simplified narrative. This trial will take time. It should take time. And in the meantime, the essential fact remains unchanged: it is Russia that invaded Ukraine, and it is Ukraine that is defending itself, with or without the gray areas of this four-year-old gas pipeline case.

The environmental shockwave no one has forgotten

An underestimated ecological disaster

Beyond the geopolitical dimension, we must remember the scale of the ecological disaster caused by the Nord Stream sabotage. The September 2022 explosions released record quantities of methane into the atmosphere, a greenhouse gas whose warming potential far exceeds that of carbon dioxide over a twenty-year period. Scientists have called it the largest single human-caused methane leak ever recorded, a fact that gives this legal case a dimension extending well beyond the geopolitical rivalry between Berlin, Kyiv, and Moscow.

This environmental dimension, often relegated to the background in media coverage dominated by diplomatic stakes, nonetheless deserves to be part of the debate. Whoever authorized or carried out this operation, whether Ukrainian, Russian, or some combination not yet known, bears significant ecological responsibility that the Hamburg trial will also, in one way or another, have to weigh in its overall assessment of the damage caused.

A worrying precedent for critical European infrastructure

This case has also exposed how vulnerable European undersea energy infrastructure remains to sabotage operations carried out by relatively modest actors, requiring nothing more than a boat, competent divers, and military-grade explosives. Since 2022, several suspicious incidents involving undersea cables and pipelines in the Baltic Sea have been reported, fueling fears of a hybrid war waged against critical European infrastructure, sometimes attributed to vessels linked to Russia's shadow fleet.

This structural vulnerability extends far beyond the Nord Stream case alone. It raises an urgent question for NATO and the European Union: the future protection of communication cables, pipelines, and tankers moving through increasingly contested international waters. Whatever the outcome of the trial against Serhii K., this structural security gap will remain, and it concerns far more than just German-Ukrainian relations.

We talk a lot about who blew up Nord Stream, far too little about what it reveals about our collective inability to protect the infrastructure that runs our economies. That security hole will stay open long after Hamburg's verdict is handed down.

Conclusion: A letter for truth, not for comfort

What I refuse to accept in this debate

I reject two equally dishonest positions in this case. The first is to wave away the German indictment on the grounds that it serves Russian propaganda — a serious court case, pursued by an independent and allied judiciary, deserves better than reflexive denial driven by partisan loyalty. The second is to weaponize this indictment to question the overall legitimacy of Ukraine's resistance against the Russian invasion, as Moscow openly does and, more quietly, Beijing.

What I expect from what comes next

What I expect is a trial conducted rigorously before the Hamburg court, greater transparency from Kyiv as the case's details become clearer, and a collective ability, both Western and Ukrainian, to separate the question of individual responsibility of a few soldiers or officers from the far broader question of the legitimacy of Ukraine's struggle against an invasion that nothing justifies. Whatever the truth about Nord Stream turns out to be, it will change nothing about what remains the central question of this war: who invaded whom, and who is defending themselves.

This letter does not close on certainty, because the case itself does not yet offer one. It closes on a demand: that the truth, however uncomfortable for some, finally emerge from a fair trial, rather than from a media tribunal where everyone picks the verdict that serves their interests.

Columnist's transparency note

Editorial positioning

This open letter follows a clear editorial line: support for Ukraine in its defensive war against the Russian invasion, opposition to Vladimir Putin and the Russian war machine. This support does not, however, imply absolute moral immunity for every Ukrainian actor; it implies a demand for truth and transparency, even when that proves uncomfortable for the cause this columnist otherwise defends without ambiguity.
