Little is known about the son, believed to be in his late 20s, and no photos or public sightings of him have been reported since he attended a Swiss school as a teenager. After his father's stroke in 2008, however, his grooming as heir picked up speed. ... North Korean media have not mentioned the son by name, but propaganda has hinted about the virtues of transferring power to a younger generation. Kim Jong-il, who took over when his father died in 1994, began building his "military first" leadership platform 50 years ago as a teenager, official media say.... Historically, the Kim family has used party caucuses to purge political enemies, as well as proclaim long-term visions for the country. Recently, there has been an unusually large number of reports about top-ranking North Korean officials being executed, killed in mysterious traffic accidents or declared missing.... "I think [Kim Jong-un] is chosen exactly because he is young," said Andrei Lankov, a North Korea expert at Kookmin University in Seoul. "In case of his father's sudden death, Kim Jong-un -- inexperienced, without power base, embarrassingly young -- will have no choice but to obediently follow the instructions of the old guard. He will be a dictator, but merely a rubber-stamping dictator. This is what the people in the position of power want."
