Forty years after war ended, Washington begins decontamination of worst-affected areas in Vietnam

Between 1962 and 1971, the US air force dropped around 20 million gallons of the herbicide during Operation Ranch Hand. Around 4,000 villages and communes in South Vietnam were sprayed, leaving at least 4.5 million Vietnamese exposed to the substance, according to census reports taken at the time. Five million acres of farmland were destroyed in the process (the size of Yorkshire, Lancashire and Northumberland combined), of which two million remain barren today.
Early on in the campaign, US planes dropped pamphlets written in Vietnamese assuring farmers that the chemicals were harmless to humans and animals. In spite of alleged warnings from chemical companies that the herbicide was potentially harmful, the US reportedly dropped the chemical at a higher concentration than what was recommended for destroying foliage.
As a result, the Vietnam Red Cross estimates that three million Vietnamese were left suffering from spina bifida, Parkinson's and heart diseases.
