I have to say that I am amazed at the events in Egypt over the last 48 hours. Right now it really does appear as if that country is on the road to the successful conclusion of a (mostly) peaceful democratic revolution. Two weeks ago I would not have thought that possible. I knew there were reasonable Muslims out there, I just didn't think there were so many of them in Egypt of all places. It remains to be seen if the center can hold, but right now it's looking a lot more promising than I would have predicted two days ago.
I think a lot of the credit has to go to the army. I find it hard to imagine that it never crossed Mubarak's mind to use Tiananmen Square as a model for how to resolve the situation in Tahrir square. Someone high up in the army must have, either implicitly or explicitly, let Mubarak know that was not going to happen on his watch. I really want to know who that was.
