The "revolution" most often goes like this:
-groundswell for "democracy" erupts, driven by several different sources with different political ends (please note that very few of these people understand or have experienced democracy, so what results from initial proposals has no real resemblance)
-after much bloodshed, dictator government is ousted
-struggle to aim and control government ensues between these different sources
-after two or three botched elections, an extremist religious group takes over
-back to square one, with a much weaker country and opposition
Too bad religion plays such a large part in the politics of the region.
Terrorists and their supporting organizations like the Muslim Brotherhood and their outside backers like Hamas and Iran would love for this to turn totally chaotic. Make it easier to subvert any attempts at organized democracy and turn it into another Iranian type situation. Look for Mullahs and Clerics to start speaking for the "revolutionaries".
We'll see if the educated westernized Egyptians can pull this together, or the religious extremists will take over.
