U.S. war veteran Larry Vetter conducts physical therapy exercises with 18-year-old La Thanh Nghia, near Da Nang, Vietnam. Nghia and his brother Toan, 21, are third generation Agent Orange victims, the result of the U.S. military’s use of Agent Orange and other herbicides during the Vietnam War more than 40 years ago. The brothers were born healthy, but began to suffer from muscular dystrophy and other problems as they grew older. They are now confined at home as their bodies and lives waste away. The United States is paying to clean up dioxin around former American bases, but has yet to offer significant aid for victims. Jan. 5, 2013.
