I’m no expert on Egypt or the Arab world. I was in Cairo a week before the protests started, and I had no idea what was coming. Actually, that doesn’t distinguish me from the experts: no one saw this coming.
Okay, some people did call this in advance. But the funny thing about predictions is that at any given point in time, everything imaginable is being predicted by someone. They may or may not be backing it up logically. It’s a common mistake to focus on the people who got it right last time and assume they’ll be able to repeat the trick.
So rather than link to a few articles and blog posts that give deeper analysis, most of which will be proven wrong soon enough, I suggest you tune in to Al Jazeera English. (Why Al Jazeera? This is why.) They’re broadcasting live views of Tahrir Square with commentary from people on the ground and various analysts.
