In modern times tyrants have tended to be motivated primarily by ideology. So you have Pol Pot and Mao and Stalin and Hitler and Castro, all of whom were driven by fantasies of creating a higher social order. And then you have tyrants like Mobutu Sese-Sekou and Idi Amin and Papa Doc Duvalier, who were primarily motivated by greed?who were just trying to amass as much power, and have sex with as many women, and eat as much food as they could. Saddam is different in that he appears to be motivated primarily by vanity. And by this romantic fascination with Arabian history?the glory of Arabia.
