BEHIND THE LINES: The inability of the Iraqi central government to rein in the Shia militias might be dismissed as a colorful and lurid tale from somewhere distant. Unfortunately, it is not.
The militias have fired dozens of rockets at facilities where US personnel are located. They have frequently fired Iranian-supplied 107mm rockets at the US embassy in Baghdad.
