VA Treat Thailand & Vietnam Exposure the Same On May 9, 2020, Senator Boozman (R-AK), a member of the Senate Veterans Committee introduced S.1381 a bill to modify the presumption of service connection for veterans who were exposed to herbicide agents while serving in the Armed Forces in Thailand during the Vietnam era, and for other purposes. The VA Secretary shall ensure that if the Secretary creates a presumption of service connection between the occurrence of a disease and exposure to a herbicide agent while serving in the Armed Forces during the Vietnam era at a military base in Thailand, such presumption also applies to exposure to a herbicide agent while serving in the Armed Forces during the Vietnam era at any military base located in Thailand without regard to where on the base the veteran was located or what military job specialty the veteran performed.

From 1961 to 1971, the U.S. military sprayed a range of herbicides across more than 4.5 million acres of Vietnam to destroy the forest cover and food crops used by enemy North Vietnamese and Viet Cong troops.
U.S. aircraft were deployed to douse roads, rivers, canals, rice paddies and farmland with powerful mixtures of herbicides. During this process, crops and water sources used by the non-combatant native population of South Vietnam were also hit.
In all, American forces used more than 20 million gallons of herbicides in Vietnam, Laos and Cambodia during the years of Operation Ranch Hand. Herbicides were also sprayed from trucks and hand-sprayers around U.S. military bases.
Some military personnel during the Vietnam War era joked that “Only you can prevent a forest,” a twist on the U.S. Forest Service’s popular fire-fighting campaign featuring Smokey the Bear.
In addition to Agent Orange’s active ingredients, which caused plants to “defoliate” or lose their leaves, Agent Orange contained significant amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin, often called TCDD, a type of dioxin.
Dioxin was not intentionally added to Agent Orange; rather, dioxin is a byproduct that’s produced during the manufacturing of herbicides. It was found in varying concentrations in all the different herbicides used in Vietnam.
Dioxins are also created from trash incineration; burning gas, oil and coal; cigarette smoking and in different manufacturing processes such as bleaching. The TCDD found in Agent Orange is the most dangerous of all dioxins.
Effects of Agent Orange
Because Agent Orange (and other Vietnam-era herbicides) contained dioxin in the form of TCDD, it had immediate and long-term effects.
Dioxin is a highly persistent chemical compound that lasts for many years in the environment, particularly in soil, lake and river sediments and in the food chain. Dioxin accumulates in fatty tissue in the bodies of fish, birds and other animals. Most human exposure is through foods such as meats, poultry, dairy products, eggs, shellfish and fish.
Studies done on laboratory animals have proven that dioxin is highly toxic even in minute doses. It is universally known to be a carcinogen (a cancer-causing agent).
Short-term exposure to dioxin can cause darkening of the skin, liver problems and a severe acne-like skin disease called chloracne. Additionally, dioxin is linked to type 2 diabetes, immune system dysfunction, nerve disorders, muscular dysfunction, hormone disruption and heart disease.
Developing fetuses are particularly sensitive to dioxin, which is also linked to miscarriages, spina bifida and other problems with fetal brain and nervous system development.
Veteran Health Issues and Legal Battle
Questions regarding Agent Orange arose in the United States after an increasing number of returning Vietnam veterans and their families began to report a range of afflictions, including rashes and other skin irritations, miscarriages, psychological symptoms, type 2 diabetes, birth defects in children and cancers such as Hodgkin’s disease, prostate cancer and leukemia.
In 1988, Dr. James Clary, an Air Force researcher associated with Operation Ranch Hand, wrote to Senator Tom Daschle, “When we initiated the herbicide program in the 1960s, we were aware of the potential for damage due to dioxin contamination in the herbicide. However, because the material was to be used on the enemy, none of us were overly concerned. We never considered a scenario in which our own personnel would become contaminated with the herbicide.”
In 1979, a class action lawsuit was filed on behalf of 2.4 million veterans who were exposed to Agent Orange during their service in Vietnam. Five years later, in an out-of-court-settlement, seven large chemical companies that manufactured the herbicide agreed to pay $180 million in compensation to the veterans or their next of kin.
Various challenges to the settlement followed, including lawsuits filed by some 300 veterans, before the U.S. Supreme Court confirmed the settlement in 1988. By that time, the settlement had risen to some $240 million including interest.
In 1991, President George H.W. Bush signed into law the Agent Orange Act, which mandated that some diseases associated with Agent Orange and other herbicides (including non-Hodgkin’s lymphoma, soft tissue sarcomas and chloracne) be treated as the result of wartime service. This helped codify the VA’s response to veterans with conditions related to their exposure to Agent Orange.
Legacy of Agent Orange in Vietnam
In addition to the massive environmental devastation of the U.S. defoliation program in Vietnam, that nation has reported that some 400,000 people were killed or maimed as a result of exposure to herbicides like Agent Orange.
In addition, Vietnam claims half a million children have been born with serious birth defects, while as many 2 million people are suffering from cancer or other illness caused by Agent Orange.
In 2004, a group of Vietnamese citizens filed a class-action lawsuit against more than 30 chemical companies, including the same ones that settled with U.S. veterans in 1984. The suit, which sought billions of dollars worth of damages, claimed that Agent Orange and its poisonous effects left a legacy of health problems and that its use constituted a violation of international law.
In March 2005, a federal judge in Brooklyn, New York, dismissed the suit; another U.S. court rejected a final appeal in 2008, causing outrage among Vietnamese victims of Operation Ranch Hand and U.S. veterans alike.
Fred A. Wilcox, author of Scorched Earth: Legacies of Chemical Warfare in Vietnam, told the Vietnamese news source VN Express International, “The U.S. government refuses to compensate Vietnamese victims of chemical warfare because to do so would mean admitting that the U.S. committed war crimes in Vietnam. This would open the door to lawsuits that would cost the government billions of dollars.”
