Secretary of State Hillary Clinton arrived for a brief stopover in the US Pacific territory of Guam Friday to meet US troops and local Governor Felix Camacho. Several hundred troops gathered in a hangar for Clinton's arrival at the Andersen Air Force Base, where a stage was erected with a huge US flag as a backdrop alongside a RQ-4 Global Hawk unmanned aircraft. Guam will be the scene of a huge military build up in coming years as the United States takes close to 9,000 US Marines out of Japan and moves them to the territory. Clinton, who first visited Guam in 1998 with her husband, the then President Bill Clinton, is expected to spend a few hours in Guam as her plane refuels before travelling to Vietnam for the East Asia Summit.
