Civilizations at their golden age, not just of military might bnut also of science, culture, engineering, population growth; literally every measure of success: Greeks, romans, mongols, germanics, christians, even muslims during their golden age - ALWAYS lead by warriors.
Civilizations at their most degenerate as they're about to fall: ALWAYS lead by merchants, priests, or other "men of letters" rather than men of the sword.

Meanwhile, anons in this thread: "No, warriors shouldn't lead, they're retards. The court eunuchs, such as myself, should lead!"

Of course, if you're someone who's posting on an internet forum in a thread like this, you're almost by definition not someone capable of being a man of the sword, since no men of the sword would be doing stupid shit like this. But at least try to rub your two brain cells together long enough to notice the pattern, fuckshits. Schmucks.
