"There is consensus among xxxxx that, at least for the moment, none of KJI's three sons is likely to be tapped to succeed him. xxxxx considers the two youngest sons, Kim Jong-chol and Kim Jong-un, far too inexperienced and incapable of effective governance. xxxxx, observing that KJI's oldest son, Kim Jong-nam, is "too much of a playboy," Kim Jong-chol is "more interested in video games" than governing, and Kim Jong-un is simply too young. Additionally, KJI had been groomed for many years to replace his father and former North Korean leader Kim Il-Sung before the latter passed away. In contrast, xxxxx, none of the sons has received similar preparatory treatment."
