that was spontaneous to a certain extent but there were also people who had been preparing for it and forces under the radar promoting it.
The "The Arab Winter" is probably propelled by similar though opposing forces (forces that want demagoguery rather than democracy).
BTW: Does anyone know where the phrase "Arab Winter" originated? I heard Romney use it in his first speech about the embassy attacks and noticed DUers used it on the same day. Was it a Fox News meme or mentioned in other media?
