Loretta Napoleoni is an Italian born economist, author, journalist and political analyst. “She is an expert on the financing of terrorism and is well known internationally for having calculated the size of the terror economy” (Wikipedia).
Among other books, Napoleoni has authored Terror Incorporated and Rouge Economics, both available below the video. Note: Her English is good, but her accent is still heavy and she has the cadence of a holiness preacher. She’s tough to understand at times. Subtitles are available.
