A lot of people say this but I'm inclined to think that this will lead down the path of the American Revolution of 1776. The British control of the Thirteen Colonies was overthrown and a democratic federal government installed, which to this day has not been overthrown by violent radicals and replaced with a totalitarian regime.
The American revolution took place in a geographically isolated, unimportant backwater, and was instigated and led by wealthy businessmen who already effectively controlled everything. We don't see anything like it happen
anywhere else. France descended into bloody anarchy, then rose into an Imperial dictatorship, before collapsing and returning to a Monarchy, before collapsing and returning to an Imperial dictatorship under the same dictator, before collapsing and returning to the Monarchy again, before collapsing into a republic, and so on. England just slowly changed over time. Germany was overthrown by external powers and had a puppet regime put in place on both sides, though it's since grown out of it. We see, in some cases, long term stability after a revolution, but always in the hands of a particularly skilled dictator.
Cuba is kind of the best case scenario we're looking at, and my bet's on it ending up much worse.
Egypt is a poor state in the middle of the biggest clusterfuck in the already clusterfuck ridden field of global geopolitics. It is surrounded on all sides by violent radicals who have a history of seizing power wherever there is a power vacuum. It's right next to Israel, who'll no doubt meddle to keep their neighbor weakened and off balance, and not much farther from Saudi Arabia, the source of most of the funding violent radical groups receive.
