"For example, the original war plan envisioned the U.S. troop presence in Iraq being cut to 30,000 by the fall of 2003. Last year, some top U.S. commanders thought they would be able to significantly cut the U.S. troop level in Iraq this year -- a hope now officially abandoned. More recently, the U.S. military all but withdrew from Baghdad, only to have to have to reenter the capital as security evaporated from its streets and Iraqi forces proved unable to restore calm by themselves."
