If the two Shi'ite factions are not fighting each other they will have more time to fight the US and the Sunni. That will be critically important if the lunatics in charge actually do attack Iran. The largely Shi'ite security forces the US has armed and trained will turn on the US troops.The bottom line is that the Iraqis have had it with the US occupation. Over 70% of the people want the US out and think that it's OK to kill Americans. The Iraqi government has given the Blackwater cowboys six months to get out of Dodge. How much longer before the give the US occupation forces a deadline and we have another helicopter on the roof moment, this time in the Green Zone.
To further complicate things we have this, the Southern supply routes (and escape route) is about to be cut off.
British pullout in Iraq leaves Basra in chaos
WASHINGTON - The British troop pullout from Iraq announced yesterday leaves Basra, Iraq's second largest and most strategically important city, in near total chaos both politically and militarily.
It comes at a time when at least four Shia militias are fighting over the city, which is surrounded by most of the nation's tremendous oil reserves and provides Iraq's only gateway to the sea.
Equally vital for U.S. strategists, the city also controls the southern portion of the road from Kuwait to Baghdad, along which mostly all U.S. supplies are brought in.
