Vietnam, US still in conflict over Agent Orange

Her children are 21 and 16 years old, but they still cry through the night, tossing and turning in pain, sucking their thumbs for comfort. Tran Thi Gai, who rarely gets any sleep herself, sings them a mournful lullaby. "Can you feel my love for you? Can you feel my sorrow for you? Please don't cry." Gai's children - both with twisted limbs and confined to wheelchairs - were born in a village that was drenched with Agent Orange during the Vietnam War. She believes their health problems were caused by dioxin, a highly toxic chemical in the herbicide, which U.S. troops used to strip communist forces of ground cover and food.
