What's happening

One hypothesis considered: Russia's military capabilities lag behind Western standards, and its economy is faltering; despite Russia's partial ownership stake in the Nord Stream pipelines, some analysts question Russian responsibility for the sabotage, noting it would be paradoxical for Russia to sabotage the pipelines it had already shut down, and arguing that Russia has now lost the opportunity to use restoration of gas supplies to Europe as leverage for concessions from the West.

Key drivers

  • One hypothesis considered: Serhii K's role as on-board coordinator directly supports the state-directed hypothesis by placing him in a leadership position overseeing the operational execution of the sabotage.
  • A former Ukrainian special operations commander coordinating the explosions directly supports Ukrainian state-directed operation and discriminates it from non-state and foreign actors.
  • Use of forged documents to charter the sabotage vessel indicates sophisticated operational tradecraft and planning consistent with state-level organization rather than freelance actors.
  • One hypothesis considered: Denial by Ukraine's military commander that he carried out or adjusted the sabotage plan cuts against the hypothesis that the Ukrainian state directed it, though state involvement remains possible if others did.

Key questions

▸

One hypothesis considered: Did Russia sabotage the Nord Stream pipelines, or do other actors remain plausible?

One hypothesis considered: Evidence suggests: Russia sabotaged the pipelines to stop Europe negotiating over gas

Ranks compare these explanations against each other; the parenthetical is how likely each one is on its own.

Weighing the available reporting, these explanations rank by evidence:

Most likely: One hypothesis considered: Russia sabotaged the pipelines to stop Europe negotiating over gas (very likely)

Best case for One hypothesis considered: Russia sabotaged the pipelines to stop Europe negotiating over gas
  • If the Nord Stream leaks result from sabotage, it was motivated by Russia's intent to punish Europe for sanctions and destroy alternative gas routes.
  • Russia has lost the opportunity to offer easy restoration of gas supplies to Europe in exchange for concessions from the West due to the Nord Stream sabotage.
Supporting evidence
  • Russia has lost the opportunity to offer easy restoration of gas supplies to Europe in exchange for concessions from the West due to the Nord Stream sabotage. One hypothesis considered: Permanent destruction eliminates Russia's option to restore supplies as negotiating leverage, directly supporting the claim that sabotage ended this negotiating opportunity. 1 source, analysis
  • If the Nord Stream leaks result from sabotage, it was motivated by Russia's intent to punish Europe for sanctions and destroy alternative gas routes. Punishing Europe and destroying alternative routes aligns with eliminating gas negotiation leverage as the hypothesis claims. 1 source, analysis
Challenging evidence
  • Russia's partial ownership of the Nord Stream pipelines casts doubt on theories of Russian responsibility for the sabotage. Russian partial ownership makes self-sabotage financially irrational, yet the hypothesis requires deliberate action despite this economic logic problem. 1 source, editorial
  • If Russia committed the sabotage of Nord Stream pipelines, it would be bizarre because Russia had already shut supplies off. One hypothesis considered: The proposition notes Russia had shutdown supplies already available; deliberate sabotage would be redundant unless the goal was permanent elimination of a negotiating card, which the hypothesis accepts. 1 source, named source
▸

One hypothesis considered: Would Russia actually benefit from the pipeline sabotage, or has it backfired strategically?

One hypothesis considered: Evidence suggests: Sabotage wouldn't help Russia—damage likely came from elsewhere

Ranks compare these explanations against each other; the parenthetical is how likely each one is on its own.

Weighing the available reporting, these explanations rank by evidence:

Most likely: Sabotage wouldn't help Russia—damage likely came from elsewhere (very likely)

Best case for Sabotage wouldn't help Russia—damage likely came from elsewhere
  • Russia is attempting to use the Nord Stream sabotage to leverage the force majeure clause to void contractual obligations and avoid penalties.
  • If Russia committed the sabotage of Nord Stream pipelines, it would be bizarre because Russia had already shut supplies off.
  • Russia has lost the opportunity to offer easy restoration of gas supplies to Europe in exchange for concessions from the West due to the Nord Stream sabotage.
Supporting evidence
  • Russia is attempting to use the Nord Stream sabotage to leverage the force majeure clause to void contractual obligations and avoid penalties. Using force majeure to void obligations is reactive damage-control, not the proactive leverage a saboteur retains—suggesting Russia must manage an unwelcome constraint. 1 source, analysis
  • Russia has lost the opportunity to offer easy restoration of gas supplies to Europe in exchange for concessions from the West due to the Nord Stream sabotage. One hypothesis considered: If Russia already controlled the outcome through shutdowns, deliberately destroying pipelines to then use force majeure would sacrifice leverage Russia already possessed—making sabotage operationally pointless. 1 source, analysis
  • If Russia committed the sabotage of Nord Stream pipelines, it would be bizarre because Russia had already shut supplies off. One hypothesis considered: Russia halted gas flow before any sabotage, so destroying pipelines would serve no purpose if Russia wanted supplies restored as a bargaining chip. 1 source, named source
Challenging evidence
  • The pipeline explosions represent a warning from Russia about energy supplies to Europe heading into winter. One hypothesis considered: If Russia intentionally used pipeline destruction as a warning to Europe, sabotage would serve a strategic purpose—contradicting the claim that it would not help Russia. 1 source, analysis
  • If the Nord Stream leaks result from sabotage, it was motivated by Russia's intent to punish Europe for sanctions and destroy alternative gas routes. One hypothesis considered: A Russian motive to punish Europe and destroy gas routes contradicts the hypothesis that sabotage would not help Russia—if punishment and disruption were the goals, sabotage would serve them. 1 source, analysis

One hypothesis considered: Who carried out the September 2022 Nord Stream pipeline sabotage?

No clear answer yet

Ranks compare these explanations against each other; the parenthetical is how likely each one is on its own.

Weighing the available reporting, these explanations rank by evidence:

Leading: Ukrainian state-directed operation (unlikely)

Best case for Ukrainian state-directed operation
For: Ukrainian state-directed operation
  • Serhii K is accused of acting as the on-board coordinator and team leader for a team that placed explosive devices on the Nord Stream pipelines near Denmark's Bornholm Island in September 2022, not as a diver or bomb expert. One hypothesis considered: Serhii K's role as on-board coordinator directly supports the state-directed hypothesis by placing him in a leadership position overseeing the operational execution of the sabotage. 1 source, verified
  • U.S. Navy divers planted remotely triggered explosives on the Nord Stream pipelines during NATO exercises in June 2022. US Navy diver involvement directly supports US/allied hypothesis and makes state-Ukrainian operation implausible; if true, it strongly discriminates against this account. 1 source, named source
  • A Norwegian surveillance plane dropped a sonar buoy that triggered the C4 explosives on the Nord Stream pipelines on September 25, 2022. Norwegian aircraft triggering charges is evidence for US/allied operation; directly discriminates against Ukrainian state hypothesis. 1 source, named source
  • Serhii Kuznietsov served in Ukraine's Special Operations Forces. The charged suspect's service in Ukraine's special operations forces strengthens the case for Ukrainian state-directed operation by linking him to the state apparatus, distinguishing this from independent actors. 1 source, named source
  • Colonel Roman Chervinsky, a former commander in Ukraine's Special Operations Forces, coordinated the Nord Stream pipeline explosions. A former Ukrainian special operations commander coordinating the explosions directly supports Ukrainian state-directed operation and discriminates it from non-state and foreign actors. 1 source, named source
Challenging evidence
  • Valery Zaluzhnyi denied the accusation that he carried out the Nord Stream sabotage after adjusting the plan. One hypothesis considered: Denial by Ukraine's military commander that he carried out or adjusted the sabotage plan cuts against the hypothesis that the Ukrainian state directed it, though state involvement remains possible if others did. 1 source, named source
  • Mikhaylo Podolyak, Kyiv presidential advisor, stated that the Nord Stream 1 leaks were a terrorist attack planned by Russia and an act of aggression towards the European Union. Podolyak blames Russia, not Ukraine; this statement denies rather than supports Ukrainian responsibility. 1 source, named source
  • Western countries sabotaged the Nord Stream pipelines. 1 source, named source
  • Wall Street Journal investigation alleged that President Volodymyr Zelensky initially approved the Nord Stream sabotage plan but ordered Commander-in-Chief Valery Zaluzhnyi to halt it after receiving a CIA warning. Zelensky's alleged initial approval followed by reversal undercuts the claim of ongoing state direction; operation proceeded despite reported halt order. 1 source, named source
  • Denmark and Sweden dropped their probes into the Nord Stream explosions in 2024 without holding anyone to account. One hypothesis considered: Denmark and Sweden dropping their probes without charges suggests weak evidence for the state-directed operation, contradicting the theory that the sabotage was a deliberate state act. 1 source, multiple independent

Less likely: Ukrainian-linked operation not directed by the state (very unlikely)

Best case for Ukrainian-linked operation not directed by the state
For: Ukrainian-linked operation not directed by the state
  • Serhii K is accused of acting as the on-board coordinator and team leader for a team that placed explosive devices on the Nord Stream pipelines near Denmark's Bornholm Island in September 2022, not as a diver or bomb expert. 1 source, verified
  • German investigators found evidence linking Kuznietsov to the sabotage operation on his cell phone. 1 source, named source
  • The German military training of at least one sabotage suspect raises questions about whether the Bundeswehr had knowledge of or facilitated the operation, or whether state support for Ukrainian military capabilities extended to training operatives subsequently identified in the sabotage. German military training of a suspect directly discriminates this hypothesis from Russian state responsibility by suggesting Western-aligned Ukrainian personnel with institutional backing. 1 source, analysis
  • German investigators claim that a team of divers from the yacht Andromeda carried out the attack against the pipelines. A team of divers from yacht Andromeda carrying out the attack is a core element directly supporting the non-state Ukrainian operative hypothesis. 1 source, named source
  • The investigation's findings suggest a coordinated operational structure with multiple specialized roles including diving experts, operational commanders, financial backers, and military-trained personnel, indicating planning and training infrastructure beyond individual initiative. A coordinated structure with multiple specialized roles strongly supports Ukrainian-linked non-state operation rather than Russian state control, which would show different organizational fingerprints. 1 source, analysis
Challenging evidence
  • Seymour Hersh published a report claiming the U.S. Navy carried out the Nord Stream pipeline sabotage with Norwegian assistance. 1 source, verified
  • Wall Street Journal investigation alleged that President Volodymyr Zelensky initially approved the Nord Stream sabotage plan but ordered Commander-in-Chief Valery Zaluzhnyi to halt it after receiving a CIA warning. WSJ's account of Zelensky approving then halting the operation contradicts the state-unauthorized hypothesis, suggesting state involvement or knowledge rather than independent action. 1 source, named source
  • The Nord Stream sabotage operation required significant technical expertise and heavy equipment such as cranes to install the sabotage devices. The requirement for significant technical expertise and heavy equipment argues against non-state actors executing the operation, undercutting the independent-team hypothesis. 1 source, named source
  • Italy's Supreme Court struck down a decision to extradite Kuznietsov to Germany in October 2025. 1 source, verified
  • Ukraine's Prosecutor General's Office has not established Ukraine's involvement in the sabotage of Nord Stream 1 and 2 pipelines. 1 source, verified

Less likely: Not established on the available evidence (very unlikely)

Less likely: United States or US-allied operation (almost certainly not)

Best case for United States or US-allied operation
  • Seymour Hersh published a report claiming the U.S. Navy carried out the Nord Stream pipeline sabotage with Norwegian assistance.
  • U.S. President Joe Biden said damage to Nord Stream was a deliberate act of sabotage.
  • Vladimir Putin blamed the US and its allies for blowing up Nord Stream pipelines.
For: United States or US-allied operation
  • Serhii K is accused of acting as the on-board coordinator and team leader for a team that placed explosive devices on the Nord Stream pipelines near Denmark's Bornholm Island in September 2022, not as a diver or bomb expert. Charges that Serhii K coordinated Ukrainian operatives on-site directly discriminates the US-allied hypothesis against Ukrainian-operation hypotheses. 1 source, verified
  • President Joe Biden stated on February 7, 2022 that if Russia invades Ukraine there will no longer be a Nord Stream 2 pipeline and the U.S. will bring an end to it. Biden's February 2022 statement that the US would eliminate Nord Stream 2 if Russia invaded is the single most discriminating piece of evidence: it establishes motive, intent, and pre-positioning unique to the US-allied hypothesis, distinguishing it decisively from Russian or Ukrainian responsibility. 1 source, verified
  • President Biden stated on the eve of the explosion of the Nord Stream pipelines that the United States would stop gas deliveries via Nord Stream. Biden's pre-explosion statement that the US would stop Nord Stream gas deliveries directly suggests foreknowledge and supports the US operation hypothesis. 1 source, named source
  • The German prosecution links the Nord Stream pipeline attacks to official Ukrainian state decision-making through allegations that Serhii K, a Ukrainian army officer, acted on behalf of Ukrainian state authorities. German prosecution's link to official Ukrainian state decision-making directly supports and discriminates this hypothesis from the U.S. or independent-actor alternatives. 1 source, verified
  • U.S. President Joe Biden said damage to Nord Stream was a deliberate act of sabotage. One hypothesis considered: Biden's explicit statement that sabotage occurred is a key piece of US awareness; combined with Hersh's reporting of Biden approval, this strongly supports the US-allied hypothesis against alternatives. 1 source, verified
Challenging evidence
  • Peter Szijjarto cited the explosion of the Nord Stream pipeline as the first act undertaken to achieve the goal of excluding Russian gas and oil from Europe. 2 sources, primary
  • The Seymour Hersh allegation that the United States carried out the Nord Stream sabotage is contradicted by the Pentagon's official denial of US involvement. Pentagon denial contradicts Hersh's allegation of US approval, undermining the evidence base for US involvement claimed in the hypothesis. 2 sources, multiple independent
  • Marcus Frohnmaier stated that the Nord Stream sabotage was probably organised at the state level. 1 source, named source
  • Hersh's reporting on the Nord Stream operation represents a successful narrative that transcribes a compelling story from someone unknown to the general public rather than proved investigative journalism. Framing Hersh's reporting as narrative rather than proof undermines the evidence base for the US-operation hypothesis. 1 source, analysis
  • Seymour Hersh alleged that Turkey, not Russia, was behind a chemical weapons attack in Syria. Hersh's history of misdirected blame on Turkey for Syrian chemical weapons suggests he may have misattributed responsibility in past reporting, undermining confidence in his Nord Stream attribution to the US. 1 source, named source

Least likely: Russian state responsibility (almost certainly not)

Best case for Russian state responsibility
  • Serhii K, a 49-year-old Ukrainian national suspected of involvement in the Nord Stream sabotage, was arrested in Italy in August.
  • Magdalena Andersson stated that intelligence from Sweden and Denmark indicated the Nord Stream leaks were probably a deliberate act of sabotage.
  • U.S. Energy Secretary Jennifer Granholm stated that it seemed Russia was responsible for the Nord Stream sabotage and that the incidents were highly unlikely to be coincidence.
For: Russian state responsibility
  • Magdalena Andersson stated that intelligence from Sweden and Denmark indicated the Nord Stream leaks were probably a deliberate act of sabotage. One hypothesis considered: Swedish Prime Minister stating that intelligence from Sweden and Denmark pointed to deliberate sabotage lends weight to Russian responsibility when combined with European security observations of Russian naval assets near the site. 1 source, verified
  • Authorities found traces of explosive material, fingerprints and DNA samples aboard the yacht Andromeda, which they matched with available samples including fingerprints from a visa application one suspect submitted for the Netherlands. Physical evidence traced to Andromeda yacht and matched to Ukrainian suspects directly implicates Ukrainian actors, excluding Russian responsibility. 1 source, analysis
  • Serhii K, a 49-year-old Ukrainian national suspected of involvement in the Nord Stream sabotage, was arrested in Italy in August. One hypothesis considered: Arrest of Ukrainian national suspected of sabotage coordination directly implicates Ukraine, contradicting Russian state culpability. 1 source, verified
  • Serhii K has denied being part of the sabotage operation, stating instead that he was a member of the Ukrainian armed forces and in Ukraine at the time of the Nord Stream explosions in September 2022. One hypothesis considered: Serhii K's denial and claim to have been in Ukraine during the sabotage directly contradicts evidence he coordinated the attack, supporting Russian state responsibility by eliminating the Ukrainian-state-directed alternative. 1 source, named source
  • Germany issued arrest warrants for seven Ukrainians in connection with the Nord Stream sabotage. Arrest warrants for seven Ukrainian nationals specifically contradicts Russian state responsibility; Ukraine emerges as primary operational actor. 1 source, named source
Challenging evidence
  • Russia accused Ukrainian saboteurs of blowing up the Nord Stream pipelines in 2022 and suggested the attack was supported by Western intelligence services. Russia's accusation that Ukrainian saboteurs, not Russia, carried out the attack directly contradicts the Russian state responsibility hypothesis. 3 sources, named source
  • Peter Szijjarto cited the explosion of the Nord Stream pipeline as the first act undertaken to achieve the goal of excluding Russian gas and oil from Europe. 2 sources, primary
  • A 2007 Swedish Defence Research Agency review warned that one diver could set an explosive device on a Nord Stream pipeline, though the impact would be modest and unlikely to cause a large explosion. 1 source, verified
  • Serhii K is accused of acting as the on-board coordinator and team leader for a team that placed explosive devices on the Nord Stream pipelines near Denmark's Bornholm Island in September 2022, not as a diver or bomb expert. Charging a Ukrainian operative as the on-board coordinator strengthens the Ukrainian-state and Ukrainian-linked hypotheses at the expense of Russian state responsibility. 1 source, verified
  • Mikhaylo Podolyak, Kyiv presidential advisor, stated that the Nord Stream 1 leaks were a terrorist attack planned by Russia and an act of aggression towards the European Union. Podolyak's attribution to Russia is a state claim; if true, it supports Russian responsibility, but Podolyak is Ukrainian and interested. 1 source, named source
