From 1962 to 1971, the US military sprayed about 19 million gallons of herbicides over Vietnam, Laos and Cambodia. The most widely used, Agent Orange, was contaminated with the dioxin TCDD, one of the most toxic chemicals known.
As veterans reported cancers and other illnesses, the Veterans Administration for years denied nearly all claims, saying there was no proof of a link.
What the evidence shows
- Denials. Through the 1980s the VA rejected the overwhelming majority of Agent Orange disability claims.
- Industry settlement. In 1984, manufacturers including Dow Chemical and Monsanto settled a class action by veterans for $180 million, without admitting liability.
- Law and science. The Agent Orange Act of 1991 directed the National Academy of Sciences to review the evidence. Its reports have found links to a range of diseases, including several cancers, type 2 diabetes and Parkinson's disease, which the VA now presumes are connected to service.
- Vietnam. The Vietnamese government says millions of Vietnamese people were exposed. The United States has funded dioxin cleanup at former air bases since 2012.
Why it matters
Veterans who were told their illnesses had nothing to do with their service waited years for recognition, and many died before it came.
Gaslighting Sick veterans were told for years that their illnesses had nothing to do with their service, a case of institutional gaslighting. The word comes from Patrick Hamilton's 1938 play Gas Light and the 1944 film Gaslight, in which a husband dims the gas lamps and insists his wife is imagining it.
