Fits with Seymour Hersh report above. He said, CIA operators did it from USA Navy ship.
Some other reports have varied - but it is clear that some combination of USA & Ukraine did it.
In 2022, both Victoria Nuland & Criminal Biden promised that Nordstream 2 would be ended "one way or another". And then it happened.
After its destruction, USA Regime media - such as, Washington Post - floated absurd pathetic theory that Russia did it to harm themselves. No one with brain cells, bought it.
Wall Street Journal later said, Ukraine did it. Versions of that story have varied, but some versions do involve USA help & Zelensky approval.
