I wonder if the term “Eugenic” had anything to do with the first names of Roddenberry and Coon. 
The word itself is from the Greek “good birth,” and is usually translated as “noble.”
I think it’s probably much more likely that they called it the “Eugenics Wars” because one of the factions was heavily into eugenics.

Herbert! :mad:
I like the subtlety that Khan never gets that he really doesn’t have the “superior intellect”. First, despite ruling half the planet, he and his ilk did eventually get defeated, by mere normals (cisgenetics? 
mundanes? invalids? ). So he should have learned then not to underestimate mere humans.
Second, he really was upset that no one else joined his side. Just because McGivers was so easily co-opted, Khan thought that people would just flock to be lead by him. I loved how everyone in the briefing room just sat there, willing to die rather than surrender, with Khan getting more and more frustrated. Khan should have learned when he had the knife at McCoy’s throat and he didn’t cow him then. Rather, McCoy was making wisecracks. Giving tips!
Humans are not so meek as Khan thinks. They are quite resourceful, when the situation calls for it.
He was used to (together with his fellow Eugs) rallying the masses back on turn-of-the-21st century Earth of the Prime Timeline (no way he had an army or population of all-Eugs) and he never felt he was really defeated, merely robbed of his rightful triumph.
I suspect that from the materials he was able to read over those days, and very likely* from Marla herself* (both her expressions and his “reading” of her) he may have gotten the notion that over those centuries the mundanes had if anything grown weaker, softer, more PC, but their psychology still makes them crave strong order and an impressive, Alpha Male leader.
The crew of the Enterprise however is (supposedly) the elite of the elite in deep space of the mid-23d century – you may get inside the head of one weak outlier desk jockette with daddy-figure issues but many of the E’s crew “have seen THINGS, man!” that could eat Khan for breakfast (literally), and of course James T. Kirk already is The Man.
I’d love to see Khan try to defeat the Obsession creature, or Trelane, or the Tholians, or a Horta. Or the space ameba. He’d never even know what hit him.
He might have fun with Klingons, though. They speak the same “language”. He has a good chance of winning. The Romulans, on the other hand, would thoroughly own him.
Or, the Borg! Khan: You will bow to me. Borg: Resistance is futile. Khan: You will submit! Borg: shoots him with nanoprobes.
What? Spock didn’t believe in the no-win scenario?
Hypocrite. 
^ Don’t you have a warp-drive to build? 
Won’t be ready until 2061. I have plenty of time.
Unless they mature extremely quickly, there’s no time for the Judson Scott Joachim to have been conceived and born and aged to adulthood by the time of TWoK.
I recall one fanwank theory that the reason the Eugenics crew (except for Khan himself) appeared so young is they were of a later “vintage” than him, i.e. Khan was one of the first successful Eugenics products, but he ages normally. His followers are the product of further research and they age far more slowly, plus they have a few additional advantages including the ability to slowly adapt to the environment, which is why they uniformly appear to be blonde and Caucasian - this was them adapting to the low-sun environment after the disaster. “Space Seed” described Khan’s group as broadly multi-ethnic, but their phenotypes faded over time. I suppose if Ceti Alpha V had been tropical savanna, they all (except for Khan, again) would have gradually started to look black, producing melanin as a protective measure.
