I'm in no way qualified to comment specifically about Egypt. But I do have a couple small things to say about peripheral issues.
One, whenever there are stories like this on crises, it always annoys me when I see points like this (from the morning's Los Angeles Times):
Two, I found this an interesting little idea, from Matt Yglesias: "If you were an elderly dictator wracked by protests wouldn't you like to just go retire someplace nice? Turks & Caicos are lovely." Why wouldn't you? Sure, maybe you're addicted to power--but this story can only end badly, worse than the way everyone's stories end. Why not, while you still have power, take some large sum of money and go into exile?
