“How America took out the Nord Stream pipeline”

Seymour doesn’t provide any proof or any evidence. It’s argument by assertion. What he writes is plausible but without any sources or other corroborating evidence. I think it more believable that Seymour has been paid to write this by a Russian aligned entity.

I don’t know the truth of the matter and Seymour could be right. We just can’t tell from the evidence provided.

Seymour Hersh has a very credible background and reputation. Assuming he is still lucid in his age, hasn't become a senile puppet of a ghost writer, then it would be foolish to write off his claims just because he isn't telling you who his source is.

> it would be foolish

or would it be prudent to wait for evidence, to err on the side of caution ?
