Sarah Chayes ... was a correspondent for The Christian Science Monitor and National Public Radio and was assigned in 2001 to cover post-Taliban Afghanistan. But she soon decided to put aside her reporting career [to] become a key player in the attempt to bring about a sea change in US foreign policy by showing how what some see as an innocuous crime - corruption - is actually a serious threat to international security. She has seen it at work not only in Afghanistan but in other places with violent insurgencies, such as Syria, Nigeria, and Iraq. In Afghanistan, the government was really a criminal organization masquerading as a government," she says. "Its objective was amassing personal wealth, and it was doing this very well." The United States had aligned itself ... with a corrupt system by working through corrupt proxies and providing them with funds and other assets, she says. This made the US no longer a neutral player in the eyes of those being harmed by corrupt practices. In 2007 Chayes wrote a book, "The Punishment of Virtue: Inside Afghanistan After the Taliban," that showed how the corruption and "warlordism" in Afghanistan was supported by the US. It was read by academics and by those at high levels of the US military. In his final testimony to the US Senate, [former Chairman of the Joint Chiefs of Staff Michael] Mullen pointed to systemic corruption as the No. 1 challenge undermining US efforts in the region: Chayes's issue had finally entered the conversation of high-level US decisionmakers.
