North Korea's opaqueness combined with its military capabilities make the country and its leader dangerous wild cards in the international community. Brookings Senior Fellow Jung H. Pak, who led the U.S. intelligence community's analysis on Korean issues, tells the story of North Korean leader Kim Jong-un's upbringing, provides insight on his decision-making, and makes recommendations on how to thwart Kim's ambitions. In her deep analysis of the personality of the North Korean leader, Pak makes clearer the reasoning behind the way he governs and conducts his foreign affairs.
