What’s the big giant looking for. Just warning some country or would like to show military might. Since the end of the Vietnam War more than four decades ago, a US Navy aircraft carrier will set anchor in the country Monday. Publicly, the United States has portrayed the four-day visit by the USS Carl Vinson and its contingent of 5,000 sailors and aviators as an historic opportunity to enhance the budding friendship that has emerged between the two former foes. The 95,000-ton carrier is expected to anchor two nautical miles off the port of Danang, which was a key battleground during the war that ended in 1975.
