The El-ites could win a nuclear war, since they have many shelters to survive in, while the Untermensch would all perish. Such El-ites aren't nationalists, and don't care if all nations and nationals certainly would lose a nuclear war.
They'd win.
This is so true I often wonder why they haven't already done it. Perhaps the nascent technology they want to maintain their quality of life in a post-nuclear wastescape hasn't matured yet.
Thanks!
