Have you considered if human extinction could be brought about with something like cobalt bombs? https://en.wikipedia.org/wiki/Cobalt_bomb
As far as I know these aren’t in anyone’s arsenal. But if you have a nuke, making a cobalt bomb is trivial.

Overall my sense is that cobalt bombs are not practical. See also this discussion by Anders Sandberg and Carl Shulman 8 years ago:

They seem similarly skeptical about cobalt bombs.
