Iraq's Insurgency Begins

Possibility: the american war planners want an iraqi civil war.
Benefits: justification for continued presence in iraq; justification for a draft, when it becomes obvious we do not have enough troops (the argument will be bolstered by another "terrorist" attack on american soil)

long-run: Muslim peoples will unite in war against the Coalition. This will open the way for the Coalition, with sufficient armies, to take over the Muslim territories.

Basically, "let's get embroiled in a world war. we'll come out on top."
