When the [US] president writes to Kim Jong Il, the son, the Dear Leader, he doesn't call him Dear Mr President, he calls him Dear Mr Secretary. Have you ever noticed that? Why is that? Because he's not the president of North Korea, he's the head of the Communist Party, the North Korean Workers' Party and he's the head of the Army. He's not head of the state. The head of the state is his father, who's been dead for 15 years.
