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.
Analytical Questions
One hypothesis considered: Did Russia sabotage the Nord Stream pipelines, or do other actors remain plausible?
The probability in parentheses is how likely each explanation is on its own; it does not compare explanations to each other.
Weighing the available reporting, these explanations rank by evidence:
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.
Other / unknown
(almost certainly not)
One hypothesis considered: Would Russia actually benefit from the pipeline sabotage, or has it backfired strategically?
The probability in parentheses is how likely each explanation is on its own; it does not compare explanations to each other.
Weighing the available reporting, these explanations rank by evidence:
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.
Other / unknown
(almost certainly not)
One hypothesis considered: Who carried out the September 2022 Nord Stream pipeline sabotage?
The probability in parentheses is how likely each explanation is on its own; it does not compare explanations to each other.
Weighing the available reporting, these explanations rank by evidence:
Ukrainian state-directed operation
(unlikely)
Best case for Ukrainian state-directed operation
- Serhii Kuznietsov served in Ukraine's Special Operations Forces.
- Marcus Frohnmaier stated that all seven suspects in the Nord Stream case are Ukrainian citizens connected to Ukrainian military and intelligence apparatus.
- Germany's federal prosecutor filed charges against Serhii Kuznietsov, a Ukrainian national, for sabotaging the Nord Stream gas pipelines.
Ukrainian-linked operation not directed by the state
(very unlikely)
Best case for Ukrainian-linked operation not directed by the state
- Ukrainian state involvement in the Nord Stream sabotage remains unproven by evidence as of July 2026 despite German criminal charges against an individual suspect.
- Serhii K, a 49-year-old Ukrainian national suspected of involvement in the Nord Stream sabotage, was arrested in Italy in August.
- Germany issued a European arrest warrant against a Ukrainian diving instructor who allegedly was part of a team that blew up the Nord Stream gas pipelines.
Not established on the available evidence
(very unlikely)
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.
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.
