So to keep score, in the last year we've seen cables sabotaged between Finland and Germany, Lithuania and Sweden, Estonia and Sweden, Estonia and Finland. Any others I missed? You might say it's too early to call it sabotage, but the earliest two cable incidents were exactly the same, so it's hardly a coincidence at this point.
Russia warned that they were going to do this last week. I think it's pretty reasonable to conclude that 1) this was sabotage and 2) it was Russia.
Hey, hold your horses. Biden also threatened to blow up the Nord-Stream 2 pipeline, yet after the sabotage, everybody said "it was Russia". Now about this incident, to be consistent, I'm inclined to think it was the Americans.
I believe at this point we have a pretty good guess as to who sabotaged the pipeline, and it wasn't the US.
