FORWARD OPERATING BASE WALTON, Afghanistan (AP) — U.S. Defense Secretary Robert Gates is beginning two days of farewell visits to remote U.S. troop bases in Afghanistan.
He began by flying Sunday morning to a base near Kandahar City in southern Afghanistan, where he was greeting soldiers and having lunch with junior enlisted troops.
Gates, who is retiring June 30, is assessing the situation ahead of a presidential decision within weeks on the start of a U.S. troop withdrawal this summer.
