Remember how some of us were still curious about what the "mission" was? Well, apparently, it's this:
Despite an intensified congressional debate about a withdrawal timetable after last week's call by Rep. John P. Murtha (D-Pa.) for a quick pullout, administration officials say that military and political factors heavily constrain how fast U.S. forces should leave. They cite a continuing need to assist Iraq's fledgling security forces, ensure establishment of a permanent government, suppress the insurgency and reduce the potential for civil war.
Got all that? You might want to write it down in case there's a pop quiz.
