He has links in the article but those links don’t give any evidence of what he claims. For instance, he has a link to the
Gang of Eight but this doesn’t provide any evidence to what he ways. He uses links in a clever way to make it seem like he’s acquired evidence. What the linked information shows is that his assertions are plausible.
It’s plausible that the U.S. used the military personnel he claims the U.S. used so that they could avoid Congressional oversight. But where is the evidence they actually used said personnel? He references a source but my source with direct knowledge of Seymour’s work says that Russia paid him to write this.
Given Seymour’s work on Russia’s involvement in Syria I’m skeptical of him having credibility on the topic of Nordstream.
