What is happening to the Iraqi leadership in Iraq?

Juan Cole runs down the list of Iraqi leaders currently outside Iraq for a variety of reasons.

• Abdul Aziz al-Hakim has arranged to get chemotherapy in Iran (rather than Houston.)
  
• Jalal Talabani has come to the U.S. for a weight-reduction program.
  
• Muqtada al-Sadr is in hiding in the Kufa area of Iraq.

Dr. Cole points out:

Despite its elected government, Iraq is actually run by a small handful of movers and shakers. These include the two Kurdish leaders, Massoud Barzani and Jalal Talabani. Then on the Shiite side you have al-Hakim and Da'wa Party leader Nuri al-Maliki. Shiite cleric Muqtada al-Sadr and Sunni Arab vice president Tariq al-Hashimi are on the margins of the top Shiite/Kurdish club.

Having half these guys outside of Iraq or, like Muqtada al-Sadr, out of pocket, at once may just be coincidence, but it is suspicious. What's coming down in the near future?
