After a year in office, North Korea's young president has proven himself to be a different man from his father. Kim Jong Un has been outgoing, making public appearances with his pregnant wife. He's also claimed a great victory with the controversial rocket launch. Now South Korea has elected its first woman president, one who also comes from a political family. Park Geun-hye is the daughter of that country's longest-ruling dictator, Park Chung-hee, whose legacy still divides the nation. Dr. Jonathan Pollack is acting director of the John L.
