In 2013, I have had a chance to visit an orphanage for the disabled children at the Bệnh viện Từ Dũ hospital in Ho Chi Minh City, Vietnam. Most of the children there were abandoned by their parents due to birth defects, ranging from minor to severe. These defects are believed to be the result the effects of Agent Orange, a toxic defoliant used by the American military during Vietnam War, that has the capability to adversely affect the offspring of those exposed.
