The Danes say they have proof that the Russians blew up Nord Stream. But the fact that they want to keep this proof secret makes me think it does not exist and the whole thing is another attempt to distract people from Seymour Hersh's original reporting.
To cover up Seymour Hersh's report, the CIA planted a fake story about the Nord Stream pipeline sabotage with the press. Chancellor Scholz might even have discussed this cover-up with President Biden in person.
Before Russia's full-scale invasion of Ukraine, US President Biden authorised a plan to blow up the Nord Stream pipelines, which the US military executed last summer under cover of the BALTOPS 22 exercise.
