Buildup in Iraq Needed Into ’08, U.S. General Says

WASHINGTON, March 7 — The day-to-day commander of American forces in Iraq has recommended that the heightened American troop levels there be maintained through February 2008, military officials said Wednesday.

The White House has never said exactly how long it intends the troop buildup to last, but military officials say the increased American force level will begin declining in August unless additional units are sent or more units are held over.
