After listening to various talking heads on Charlie Rose, and the Newshour, I think the situation is getting worse not better.
Yeman basket case in the past, slightly worse with the President being wounded.
Bahrain formerly stable government, keeping a tight lid on a highly pissed off population, with additional problems of Shia, Sunni tensions. Modest oil producer
Libya, formerly stable police state, now engaged in a civil war with no signs of ending soon, significant oil producers
Syria formerly very stable police state, standing on the bring of a civil war. No hope of a quick resolution
Egypt formerly stable government moderate with respect to Israel. Now they have accomplished the easy goal getting rid of Mubbark, but have made little traction in forming any type of government.
Compared to the situation say a several months ago. We have replaced a couple of potential civil wars, Tunisia and Egypt, with 3 actual civil wars. And neither Tunisia or Egypt are out of the woods.
