Turns out that there is now a German arrest warrant out for a Ukrainian diving instructor who is thought to have helped blow up Nordstream. And 2 other Ukrainian diving instructors are people of interest.
Of course, the Guardian being the Guardian has to say
It remains a mystery who was behind the explosions that destroyed three out of four pipelines, which became a symbol of German reliance on gas from Russia after its invasion of Ukraine in February 2022, and Russia and the west have accused one another of being responsible. Each has denied involvement.
No, no it does not. I've yet to hear one valid reason from anyone as to why Putin would sabotage the pipelines when he can (and I believe did) just turn them off. And now there's an arrest warrant for one Ukrainian, at least 2 more are being investigated and you STILL say "oh, we don't know who did it?"
It was demonstrated that the US did it long ago. Even from the first few days someone tracked a US mil airplane and showed a flight path consistent with a bomb release over the pipeline - later it was found that the only thing that guy got wrong was that it wasn't a depth charge, it was a radio transmitter to set off already planted charges.
I'd point to the simpler piece of evidence that Biden told everyone on video that he was going to destroy the pipeline, before somebody destroyed the pipeline. You don't have to be a superdetective to find the shooter when the first suspect is the guy who said "I am going to kill you."
That is strong circumstantial evidence, but it's not proof. When you're arguing this kind of thing, proof is king. The military operation is proof.
