Gregg on North Korea Succession

Dec. 19 (Bloomberg) -- Donald Gregg, former U.S. ambassador to South Korea, talks about the future of North Korea after the death of dictator Kim Jong Il. The likely succession of Kim's little-known third son, Jong Un, threatens to trigger a dangerous period for the Korean peninsula, where 1.7 million troops from the two Koreas and the U.S. square off every day. Gregg speaks with Rishaad Salamat on Bloomberg Television's "Asia Edge." (Source: Bloomberg)
