This is a system that is set up to have one man in charge. There's no indication that the change in leadership has changed anything in terms of the nature of the dictatorship there.
Very clearly the new leader is from a different generation. One of the things I found interesting is that we found out he has a wife, who appeared with him in public on a number of occasions. We've never found out information like that about other North Korean leaders. Whether these are significant changes or whether they are simply appearance changes, we're watching carefully and hoping to see.
