Who Blew Up the Nord Stream Pipeline?

Who Blew Up the Nord Stream Pipeline?
Jeffrey Sachs is pretty blunt about it: "The US blew up Nord Stream."

So, how does he know? His reasoning is straightforward: "They said they would, and they did it."

Here are some key points:

Back in February 2022, Joe Biden told the press that if Russia invaded Ukraine, Nord Stream would be done for.
Multiple US officials, like Victoria Nuland, made it clear that Nord Stream would be stopped or destroyed.
There were records of US planes near the site when the explosion happened.
Radosław Sikorski, who was Poland's Foreign Minister and is again now, tweeted "Thank you, USA" with a picture of the gas leak from the Nord Stream explosion.

Pretty compelling stuff, right?
