“How America took out the Nord Stream pipeline”

Seymour doesn’t provide any proof or any evidence. It’s argument by assertion. What he writes is plausible but without any sources or other corroborating evidence. I think it more believable that Seymour has been paid to write this by a Russian aligned entity.

I don’t know the truth of the matter and Seymour could be right. We just can’t tell from the evidence provided.

If you look at all the players, their interests, and their capabilities, I think the most logical conclusion is that the US likely did it. Of course this is not evidence but this the sort of operation where success means no evidence (at least no evidence available to the public at large as it is possible and, one might hope, likely that neighbouring countries know).

Why leave one of the brand new, larger pipelines undamaged, so that Russia could then offer after the event to work with Germany to activate it? Which naturally they did.

This pipeline had been completed but activation was stopped due to the start of the war. If Germany had capitulated and activated it with Russia that would be a major political win for Russia and blow for the suggested goals of the US and other allies. To me this seems to be the biggest hole in the theory that the US was responsible.
