This was stated in an exclusive interview on the RT channel by the Pulitzer Prize winner, the author of an investigation into the undermining of the Nord Streams, Seymour Hersh.
He recalled that within three weeks of the briefing at which Biden was informed about the plan, he spoke about it publicly, as did Deputy Secretary of State Victoria Nuland.
“Within three weeks [of the briefing], in late January/early February of last year, they both publicly stated, ‘We know we can stop him.
The President said this at a press conference: “We will stop Nord Stream 1.”
After these words, there was a question from a journalist.
It's all known, documented, and on the evening news.
The journalist asked: “How will you do it?”.
[Biden] responded, "I'll tell you: we know how to do it.
We can do it,” the journalist said.
This upset the group that devised the plan, "because everything was conceived as a covert operation," he stressed.
“By the time they had completed the task, they had made everything possible, they had planted explosive devices, using Navy divers, after which the explosives were just there for several months,” he said.
Hersh also said that Biden decided to undermine Nord Stream solely for political reasons, his goal was to prevent Germany and Western Europe from opening the pipeline in the event of an early onset of cold weather.
On February 8, Seymour Hersh said that US Navy divers planted explosives under Nord Stream.
In his article, he wrote that the pipelines were mined during the NATO exercises BALTOPS 22 using remotely activated devices.
