"Families participating in an American-financed irrigation project from 2002 to 2006 were promised payment in corn for clearing the land and digging canals. The Kenyan government objected to the importation of American corn because the country was awash in a bumper harvest that had caused corn prices to plunge.
The result: American officials, prohibited by law from buying the corn locally, could not deliver it. As the impoverished families waited in vain for sustenance from the American heartland, malnutrition among the youngest children worsened and five people died of hunger-related causes."
