http://www.msnbc.msn.com/id/11947773/Pentagon and military officials say Iraq's not fighting a civil war yet, but warn that Iraqi security forces and the government could still collapse, dragging the country into one. So the U.S. military is drafting a series of contingency plans to deal with that very ominous possibility.
Military officials tell NBC News the first objective, however, is to head off a civil war. The U.S. military hopes to keep Iraqi security forces from taking sides in the sectarian violence by pressuring the Iraqi government to crack down on any rogue elements within the police or military.
The second option: U.S. forces could again be sent into combat against sectarian militias, which military officials say would require an increase in the number of American soldiers and Marines in Iraq.
And the last resort, if violence is spinning out of countrol: Military officials say they would also have to consider the possible withdrawal of American forces.
