Iraq's Unraveling?, Ctd.

Tom Ricks quotes retired Col. Pete Mansoor, Gen. Petraeus's executive officer in Iraq during the surge:

As I recall what I said was that the status of forces agreement would put U.S. forces into a position where they could not intervene to stop the government of Iraq from attacking the [Sons Of Iraq].  If the Iraqi Security Forces needed help once engaged against the SOI, U.S. forces could be drawn into the fight against the very people who helped us turn the war around. I certainly hope this doesn't come to pass, but given what we've just seen happen in Baghdad, the possibility is disturbing.
