Iraqi officials say they’ve reached a tentative agreement on the withdrawal of US troops. Iraqi and US negotiators are said to have agreed on a plan that would remove US troops from Iraqi cities by next July and combat troops by 2011. US troops would still remain on the hundreds of American military bases around Iraq after leaving the cities and would remain immune from prosecution. The deal would face approval from the Iraqi cabinet and parliament. The Bush administration refused to discuss a timetable for withdrawal until last month. But it appears the deal could provide vague language that sees the timetables as “goals” and “horizons” rather than firm commitments.
