Baghdad in state of emergency! Why haven't we evacuated our embassy?

via NBC News.

Iraqi officials declared a state of emergency for all of Baghdad on Saturday after protesters loyal to popular Shiite cleric Muqtada al-Sadr breached the heavily fortified Green Zone, home to government buildings and foreign embassies, including the American one.
"Iraq security authorities have declared a state of emergency in Baghdad," said Brig. Gen. Saad Mann, a spokesman for the Iraqi military. "All gates that lead to Baghdad are closed. No one is allowed to enter into Baghdad, only those who want to leave Baghdad can do so.

This govt appears ripe to fall before the weekend is over.  I hope they have evacuation plans for US forces spun up.  I hope our MEU has been turned around and our carrier is prepared to provide cover to our helos evacuating our embassy...speaking of which.  WHY HASN'T THAT ORDER BEEN GIVEN!  This could turn into a tragedy if its misplayed by the Obama Admin.
