Even when I was a kid, I never understood how Trek squared its "we humans have learned to live together as peaceful beings and put aside our savage tendencies and thus we have reached the stars" pollyannaism (expressed even more strongly with the Vulcan variant of "we learned to completely subjugate all emotion--positive and negative--in order to survive") with the plethora of right bastards that seemed to have avoided nuclear self-destruction and made it to the stars just fine without such a species-wide awakening, particularly the Romulans, who seem to be the living proof that Surak was a blue-nosed fuddy-duddy.
(Damn. That's a long-ass sentence right there, that is.)
