In 2010, a former Wall Street trader flew into war-torn Sudan to negotiate a deal with a thuggish general. He had his eye on a 1 million acre tract of fertile land fed by a tributary of the Nile in the southern section of the country, a region that later claimed its independence as South Sudan. The investor, who planned to profit by developing and exporting agricultural commodities, boasted about how the region's instability was a principal variable in his financial model: "This is Africa," he told reporter McKenzie Funk, who shadowed him for a riveting piece in Rolling Stone (PDF). "The whole place is like one big mafia. I'm like a mafia head."
