Since it seems to have gone unnoticed in the thread, Yemen's President Ali Abdullah Saleh has left the country. Apparently he was in talks for a handover of power to someone in the military or senior levels of government anyways, but a rocket attack on the compound he was at sorta accelerated things.
He's now recovering from injuries in Saudi Arabia. He has not formally renounced power, but it's difficult to imagine him coming back to Yemen without all-out war erupting. (Although Saudi TV is reporting that he is planning to return...) Even the rank-and-file in the military and police have reportedly been celebrating his departure. So now the question is...what next? Yemen was on the verge of a Libyan-style civil war, with a loose coalition of armed tribes fighting the government security apparatus. The leaders of said tribes are all now in various political parties that have sprung up, and it's those political parties which are going to hammer out how to hold a democratic election and field the candidates for it.
Because of the fractious nature of Yemen's tribal politics, this thing has massive clusterfuck written all over it. But I do wish them well.
So...the Arab dictator watchlist stands as:
Tunisia: Gone.
Egypt: Gone.
Yemen: Gone.
Libya: In progress, stalled.
Syria: Simmering hot, but suffering from distinct lack of weapons for the opposition and lack of fractures within the ruling elites.
Bahrain: Effectively quelled.
Most of the other countries in the region have found that buyoffs (everybody gets a $100 check this month!), promises of reform and maybe a few shufflings of Cabinet members have been effective in calming things down.
