But at this point, the article is basically "cool story, bro". The only independently verifyable bits are the public statements of Biden, Nuland, etc, which are already well-known. But those only show that the US really really really didn't like the pipelines - and that was never a secret. They do not give any evidence for a planned operation to destroy them.
The rest of the article is amazingly detailed but only based on an anonymous source. Even if we trust that the source existed, there is no way to know if that source itself is trustworthy.
So as of now, I don't the information in the article would convince anyone of the "US did it" hypothesis who wasn't already convinced.
I think the only thing that the article is useful for is as a future reference. It could be useful to remember the details and keep an eye if they match with any future developments.
