If history's any judge, you might have democratic leanings in a revolution but that doesn't necessarily mean that the revolution is going to end up with democratic results.
Demographics don't lie, economies don't lie. When the median age of your population is twenty-four-years-old and a quarter of the working population's unemployed - this is not a recipe for success.
Social media is important, but it does not bring down governments. Governments can shut down the Internet. Governments can control media access. If they do what the Tunisians did and try and negotiate with the opposition, then the media's still open, the international community can learn what's happening in the country, and then that can provide inspiration. But in mid-2009, the Iranian regime just shut down the Internet. Facebook went dark. Twitter went dark. BBC Persian, Voice of America, Persian News Network all went dark. That was it.
The fundamental truth is that the guys with the guns matter more than most.
One of the things that makes me the most nervous is that the Middle East has historically had a sense of predictability. You may have a terrorist incident or you may have a revisionist regime like the Iranians, but on the whole, the region is twenty countries. On the whole, you go to bed and you wake up and you have a pretty good idea that most of those twenty are doing just fine, you don't have to pay attention to them. There's some stuff going on but you don't have to worry about a governmental overthrow that will suddenly force you to evacuate your embassies.
