It takes two people to fire any of the nuclear weapons in the US (or Russian, or I believe any of the others') arsenal. A ballistic missile submarine only needs two people to turn their keys. And yet, that's enough to keep us from having a bunch of missiles wiping out several million people (and potentially provoking other strikes that cause millions more to die).
You're never going to be completely able to eliminate all risk. Even if you made it ten people, well, it's still theoretically possible that you could have a ten person suicide pact if they'd all secretly joined some sort of cult - but the risks are far, far lower. Having one person be a suicidal narcissist who's managed to escape screening or otherwise arouse suspicion is far more likely than two people doing so, who are in the same position to do something like this.
