In 1961, South Vietnamese president Ngo Dinh Diem asked the United States to help defoliate the lush jungle that was providing cover to his Communist enemies. President John Kennedy acquiesced and formally launched Operation Ranch Hand, the United States Air Force’s program of systemic defoliation with the chemical compound Agent Orange. So many years later, we’re still coming to grips with the devastating effects of Agent Orange on troops and civilians alike. Decades of the government dragging its feet on dealing with the Agent Orange issue in any comprehensive way has delayed a full reckoning. New information about diseases caused by the defoliant trickle in year by year while clean-up efforts continue in Vietnam itself. The entire Agent Orange saga provides a casebook study in how not to deal with the health and environmental fallout of combat.
