In ancient Greece, the barbarians were those outside of the empire who did not speak the language of civilization. They were savage invaders seeking to pillage the wealth and culture of the empire.
Today the barbarians emerge from inside the empire and spread outward. The imperial leaders have engaged in serial wars of destruction and pillage, even as their own societies and economies wallow in ignorance, misery, debt, addiction and criminality. Imperial barbarians devastate whole cultures, erasing the great historical legacy of ancient civilizations like Iraq and Syria, while imposing their culture of morons, drugs and electronic gadgets, which has already infantilized its own population.
