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.
