"Lucan Way, a professor of political science at the University of Toronto, said another contributor to regime fragility that would be worth factoring in to a more sophisticated analysis is whether the authoritarian government is itself the product of recent revolutionary struggle. Dictatorships run by an ideologically united revolutionary party – Iran, for instance, and to a lesser extent China – are, Dr. Way argued, more durable than those whose rulers rely purely on guns and patronage."

I wonder if Egypt's leadership was the product of a revolutionary struggle? To some extent there was a movement, and it was more recent than China's revolution - but it was also a lot smaller. Egypt did have a general strike in January 1952. Tunisia also had one.
