Le Thi Thu, 42, and her daughter, Nguyen Thi Ly, 11 sit outside their home in a village south of Da Nang, Vietnam. They are second and third generation victims of dioxin exposure, the result of the U.S. military's use of Agent Orange and other herbicides during the Vietnam War more than 40 years ago. Despite their facial deformities and other health problems, Thu says she never feels anger at what has happened to herself and her daughter. "I'm not angry with anybody just because Vietnam had a war," she says. "A lot of people suffered. Sometimes I feel sad, but I'm not angry with anybody." May 28, 2012.
