There is some talk that the troubles in Tunisia were warmed up a bit by a wikileaks revelation of a state department document detailing just how corrupt the buggers there were. Not the main factor, but fanned the flames a bit.
Gaddddaffffi (delete consonants to taste) might hold on a while through great brutality. A lot of other African and Middle eastern dictators would like to see it happen, to stop the momentum and scare the mobs. I hope you are right, though.
Heck, if we're speculating, do you think there is any chance this democratic movement might spread as far as the USA?
