My team at DarkOwl did a ton of work researching, discussing, and debating this piece, https://www.darkowl.com/blog/nation-state-actors-in-the-dark-web. My role was editor, debater, and shepard to find a path forward. There are two people who did the bulk of the work on this, and have asked not to be named, but the credit goes to them.
As we state in the essay,
As one would suspect, nation-state actors are not immediately apparent on the dark web.
There is no smoking gun. It's a more nuanced discussion.
