““Corruption, it made plain, was not solely a humanitarian affair, an issue touching on principles or values alone. It was a matter of national security—Afghan national security and, by extension, that of the United States. And if corruption was driving people to violent revolt in Afghanistan, it was probably doing likewise in other places. Acute government corruption may in fact lie at the root of some of the world’s most dangerous and disruptive security challenges—among them the spread of violent extremism. That basic fact, elusive to this day, is what this book seeks to demonstrate.””
