in libya, for exmple, there were 80 malitias that came together and fought the battle. if you lack at syria today there are like ten or fifteen unified. they unit unifying using the tools available to them. there's no obvious natural leader who spent 30 years fighting the great fight. assuming this dictator goes, how will it be replaced? maybe thel end up with a great one or a series of six months rotating near-civil war governments. you don't know. >> it was the muslim brotherhood that was organizing the streets for thirty years. >> the muslim brotherhood is interesting. because they were secretive and because many of them were jailed and highly religious, they organized in their very charismatic. ignoring the question of social values. what's interesting about the brotherhood and the group that did in tunisia, they don't actually tell do you what they're going to do. they are very careful just like our politicians. lftd right. to not actually say what the tradeoffs they're going to make are. >> dick, how do you see the rev revolution on twitter. did you think you issu
