For planning purposes, the Army is gearing up to keep current troop levels in Iraq for another four years, a new indication that conditions there are too unstable to foresee an end to the war.

Gen. Peter Schoomaker, the Army chief of staff, cautioned against reading too much into the planning, which is done far in advance to prepare the right mix of combat units for expected deployments. He noted that it is easier to scale back later if conditions allow, than to ramp up if they don’t.

“This is not a prediction that things are going poorly or better,” Schoomaker told reporters. “It’s just that I have to have enough ammo in the magazine that I can continue to shoot as long as they want us to shoot.”

Even so, his comments were the latest acknowledgment by Pentagon officials that a significant withdrawal of troops from Iraq is not likely in the immediate future. There are now 141,000 U.S. troops there.
