38 North has a series of essays on Kim Jong-Il's rule and legacy for North Korea in the wake of his funeral (captured in all its weirdness in the above video). From James Church's thoughts on the succession process:
What is interesting about the current situation is that, for the first time in more than 50 years, there is in Pyongyang no single, dominant individual at the top to make the final decisions, to resolve different approaches among advisors, to play individuals against each other to keep the system in rough balance. As Rudiger Frank points out, Kim Jong Un apparently did not get to the point in his own political standing to be able to step into such large shoes convincingly, at least not yet. The regency group, presumably, will have to take on those responsibilities. Yet in many respects, no one in North Korea born in the past 60 years has much if any experience operating in such a decision making environment.
Under Kim Il Sung, there was at least a functioning party Politburo that was consulted on important matters. Such was not Kim Jong Il’s style, however. He did not want to hear consensus decisions—he wanted to hear what a particular leading official thought, and he called people into his office one at a time to grill them. Maybe party elders like [Supreme People's Assembly] President Kim Yong Nam or Premier Choe Yong Rim, both of whom had extensive experience working at top levels during Kim Il Sung’s reign, will be able to go back to functioning in a somewhat more collegial style, but will they have a dominant role in the inner circle around Kim Jong Un?
