Bruce Cumings. He is an American historian of East Asia, professor, lecturer and author. He is the Gustavus F. and Ann M. Swift Distinguished Service Professor in History, and the chair of the history department at the University of Chicago. His books on the Koreas were invaluable to us when we briefly visited the DPRK as a side trip from the Beijing Games in 2008. You can read my report here (with pictures by my Filipina wife Cosy): http://www.frugalfun.com/north-korea.html
Along with the Middle East, the Korean situation is a flash point for war and an area where official fabrications abound. Bernie should have advice which goes beyond conventional wisdom in this area as well. Bruce Cumings has the authority and experience to debunk nonsense about the Korean situation in general and the DPRK in particular.
