I dont think you understood my comment. I wasn't referring to the last 50 years, I wasn't even referring to 50 consecutive years.

I mean that in all human history, for a total of 50 years, has there been anywhere a leadership set that followed rational principles as opposed to platonic, subjective, or emotional ones.

All control is based around the words that wrap the violence behind them. "Controlling people with words" is as universal as it is redundant.
