True, but I think it is pretty safe to assume these revolutions are going to turn out bad given the recent history and current political, social, and economic trends in the Arab world.
I hate being metaphorical, but dawn happens after the darkest hour. I guess I'm being too optimistic.
Remember, the French revolution caused instability throughout France, led to oligopolies, terror of the civilian population, complete destruction of the social structure, an authoritarian rule, and it also led to major instability throughout Europe, not to mention that in the end, the very same government system it tried to abolish was reinstituted.
The Arab Spring is nowhere close to competing with the events of the French Revolution in terms of destruction, not yet at least.
