MCoG is primarily a show about a 16th century america road trip and mesoamerican magitech, so I really need to emphasize that the following plot point is a footnote at best. That being said, "these two civilisations, which had wealth and technology so advanced you can't even imagine, destroyed each other over a trivial matter no one even remembers in a bloody atomic war that anihilated them so thoroughly that the only things left of them are a handful of incomprehensible machines and a few sickly survivors" hits pretty hard when you remember that the show aired in the middle of the cold war.
