The first military use of Agent Orange was in 1961. There’s a new book out, called Scorched Earth: Legacies of Chemical Warfare in Vietnam. In this segment, author Fred Wilcox discusses what he’s discovered in thirty years of researching the subject: the chemical corporations knew of the dangers, congress has protected the makers of the chemical, and millions of Vietnamese and many thousands of American veterans and their families are still affected. Wilcox says there have been scorched earth policies before, but this is the first time in history a government inadvertantly poisoned its own army and is now waiting for this army to die.
