Oh...they'll say something similar to what was said about Imperial Rome, I imagine. Something like, "A once progressive democracy with representation for the common people slowly devolved into a corrupt militaristic empire under the rule of autocratic egomaniacs and despots who lived in unheard of luxury while conducting themselves as if they were gods on Earth, until they destroyed all remaining vestiges of moral decency and responsibility. At last the empire fell, gradually, under the weight of its own iniquity, decadence, and loss of belief in its original founding principles."
