What the NIE actually said

Bill Roggio expounds:

Most significantly, the NIE states that shift from a
counterinsurgency role to a counterterrorism and support role, or the “strategic
redeployment” of US forces, would squander the progress of the past year and
lead to further instability in Iraq. “We assess that changing the mission of
Coalition forces from a primarily counterinsurgency and stabilization role to a
primary combat support role for Iraqi forces and counterterrorist operations to
prevent AQI from establishing a safehaven would erode security gains achieved
thus far,” the NIE concluded.

Those who call for a premature pullout believe that will be the end of it, terrorist problem solved. In fact, giving Al Qaeda victory in Iraq will only be the beginning and I can't imagine any Party or individual will not get blamed for all the fallout that a resurgent Muslim Radicalism will bring, not only in the Middle East, but into Europe and America as well. Then there's a nuclear Pakistan and a soon-to-be nuclear Iran to contend with, likely passing on WMDs to any terrorist so inclined to further the cause of jihad.
