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".
I'd bet my last dollar that at least four nations had "blow up Nord Stream to force continued conflict" contingency plans.
Who did it? Germany, Russia, USA, Ukraine, or a curve ball from the one of the Nordic or Baltic states? We'll probably never know, and none of those answers would surprise me.
This was leaked at the time that it is now to send a message to the Germans.
[1]: Whereas analysis based on what Russia was actually doing was largely correct before the war. This is why there was such a large chasm between what the US was saying then- based on their ability to hack Kadryov's phones and hear what was being said at those levels, along with their satellites to observe what the actual Russian army was doing- and what the French and Germans were saying based largely on 'that would be a dumb thing for Putin to do'.
It is now known that Putin's decision to invade was due to bad intel from his intelligence services that reported that Ukraine would not be able to mount significant resistance. In that light it was reasonably self-interest-pursuant.
Acting on incorrect information is not the same as being irrational.
