I think the democratic process in the Arab countries will be a long one, similary to the long process ocurred to achieve democracy in western countries.
Don't forget the French revolution, 2 world wars, the american civil war, etc... how much suffering, how many millions of death and how many generations to achieve democracy in the western countries ?
The same for the Middle East, i think with the globalization the process might be shorter but anyway it might take the whole century with ups and downs.
