It's all very interesting. It's interesting to see how the situations in Tunisia, Egypt, and
Yemen all seem to derive from the same source of social power in the people: they are realizing they have power in coordinated movement against corruption and authoritarianism, and this is reinforced by what they see beyond their own situations....all happening at once it seems.
And I'll reiterate: I cannot see how this sort of thing could happen as such without the power of the Internet and social media. (With the exception, perhaps, of Yemen, whose population is quite impoverished compared to Tunisia and Egypt....but you never know.)
It would seem that a long history of authoritarianism in a few parts of the Arab world could very well come to an end. If only we could see this happen in the oil-rich nations.
