The only anchor in reality appears to be Biden suggesting that they knew how to take it out which seems like a pretty weak place to build a large story.
What I find particularly odd is that this entire thing appears to be based on a single, unnamed source "with direct knowledge of the operational planning".
But he does often rely on sources who remain anonymous: https://en.wikipedia.org/wiki/Seymour_Hersh#Use_of_anonymous...
I did find it interesting in that Wikipedia article to read that The New Yorker's editor insists on knowing the identify of all of the anonymous sources that Hersh has used when his reporting is published in that magazine. That suggests to me that while Hersh can probably be generally trusted, his work is of a higher quality when it's published in an outlet like The New Yorker, as the editor-in-chief and other staff submit it to a more rigorous internal discussion. That's in comparison to probably no internal review or discussion by Substack.
Since Nordstream was destroyed amidst public pressure from US energy companies who wanted to takeover the European energy market, the US has become the world's leading exporter of liquid natural gas, Europeans are paying record natural gas prices, and US energy companies are reporting record profits. Again, the relationship between these things should surprise nobody.

It doesn't say it outright, but if the hastily re-programmed explosives were triggered by a sonar buoy after three months in sea water as the article says, then it would not be surprising at all if some of them failed to go off.
Precisely that the article implicitly gives very plausible answers to good questions like yours, is why I think it's credible.
