Today marks 50 years since the end of the American War in Vietnam, which killed an estimated 3.3 million Vietnamese people, hundreds of thousands of Cambodians, tens of thousands of Laotians and more than 58,000 U.S. service members. But for many Vietnamese, Laotian and Cambodian people; Vietnamese Americans; and U.S. Vietnam veterans and their descendants, the impacts of the war never ended. They continue to suffer the devastating consequences of Agent Orange, an herbicide mixture used by the U.S. military that contained dioxin, the deadliest chemical known to humankind.
