U.S formally shuts down the war in Iraq

U.S. Army soldiers from the 1st Cavalry Division, based at Fort Hood, Texas, load their baggage as they begin their journey home after a deployment in Iraq, at Camp Virginia, Kuwait, Thursday. After nearly nine years and 4,500 Americans dead, U.S. officials formally shut down the war in Iraq — a conflict that Defense Secretary Leon Panetta said was worth the American sacrifice because it set Iraq on a path to democracy.
