Now what?? Ramifications are huge. The chances of a democracy forming that is recognizable to the West are very slim. Israel certainly has reason to be anxious, and the military is still in control. I would argue once again that a revolution without a foundation that champions individual liberty and limited government is doomed for failure. What failure looks like in this case is anyone's guess, but let's hope the end result is closer to Turkey than Iran.
More details here, but I'm linking to Al Jazeera so take it w/ a grain of salt. Certainly the photo of mass protesters bowing to Mecca raises questions.
UPDATE: This from Legal Insurrection: "If I were the Israelis, I'd be dusting off the old Sinai tank battle
maps and strategies, and calling on the veterans of the prior Sinai
battles for wisdom. Because at 3 a.m. there isn't going to be any help." Read the whole thing.
