ABC News Nightline Vietnam's Lingering Mystery: Agent Orange 2007 Horror Movie Reviews

In the years following Vietnam, a number of veterans were stricken with various diseases, including cancers and diabetes. In the 1980s, the Centers for Disease Control reported that veterans appeared to be dying at a higher rate than the general population, while the Veterans Administration revealed that Marines serving in Vietnam were dying of lymphatic and lung cancers at higher rates than Marines serving outside Vietnam. Despite mounting research and pressure from veterans' groups, the government refused to acknowledge a link between exposure to defoliants in Vietnam and subsequent illness. Not until 1991, when Congress enacted Public Law 102-4 (otherwise known as the Agent Orange Act), was the Veterans Administration required to presume a connection between certain illnesses and service in Vietnam. Ted Koppel and Nightline investigate the health effects of Agent Orange -- and the U.S. Air Force's management of one of the most extensive (and expensive) health studies in history.
