Revolutions are not won or started by the young, but by those that can whip up the passion and fury of the youth. Look at Obama for an example.
The mature are far more violent, but they are calculative and thoughtful about how to get it done and whom to use. The youth of a nation, particularly young disenchanted males are quick to anger wanting a quick change to their current situation.
The revolution in Egypt and the rest of the Arab countries is only beginning, the ousting of Mubarak is only a first step, the young of Egypt are now at the mercy of those that have the ability to control minds and resources.
It makes a better news story to say the young did this and that here in the West. Such is the worship of youth, a great Western god.
