WHAT WAS THAT ABOUT FAMILY DICTATORSHIPS RARELY LASTING PAST THREE GENERATIONS?: Meet the Dear Leader in waiting:

Jae H. Ku, director of the U.S.-Korea Institute at the School of Advanced International Studies at Johns Hopkins University, said there was a stark contrast between this transition of power and the one that occurred when Kim Jong Il took command after the 1994 death of his father—“Great Leader” Kim Il Sung, the nation’s founder.
Ku said the “Dear Leader” was “groomed for the job over a good 20 years” and had solidified his power by the time of his father’s death.
“Now we have a person who has been groomed for the job in less than two or three years,” he said of the Dear-Leader-in-Waiting, Kim Jong Un. “It’s amazing—we know so little about this guy. We have so little to work with.”

 Title refers to some article I remember reading that said dictatorships like the Kims do not last beyond one or two transfers of power, that I can't google back into existence at the moment. Kim Jong Un is not the guy who got arrested trying to get into Tokyo Disneyland, by the way.
