In 1975, the Vietnam War ended and the United States withdrew its troops. However, for the Vietnamese people, the destruction of the war was far from over.

This herbicide contained extremely toxic tetrachlorobenzene and dioxins (dioxin) compounds, which can cause diseases including diabetes. Various lesions within the body destroy fertility and genetics at the same time.
