Well, it was a wake-up call to the leaders of the conflicting powers. In any story about conflict, there can be intervention by a third-party to provide redirection or inspiration-- whether it's an innocent child making fighting parents feel like jerks in a mainstream story or the Organians putting the kibosh on Kirk and the Klingons in
Star Trek. In the
Odyssey storyline, the aliens didn't just stop a war in
2010, they evolved David Bowman in
2001-- to say nothing of the fact that it was the Monolith (originally Clindar) who jump-started Human evolution to begin with. I don't think it really negates optimism or Utopianism to have a mentor; even Caine had Master Po.
