No.
It wouldn’t take many of them.
A few key players is likely enough.
A few to pull off what, nuking America or Europe and create a nuclear war that destroys us all?
I think that would take more than a few, and those needed would involve a very disparate list of people, not just a small cabal within one tiny group like in a movie.
Why would people want to end themselves and how long would it take for such a plan to be built up and converts to the cause won over?
