The death of Kim Jong-il, who ruled North Korea from 1994, reminded me of something a Korean friend told me a few years ago. My friend is an expert on North Korea and told me this "for a fact." Now, I also remember many things I was told "for a fact" in Moscow in Soviet times. This is a fact I've never had the opportunity to verify (and wouldn't know where to look), so I'll put everything in quotes as my friend told it to me.
In order to facilitate his system of personal rule, Comrade Kim Il-sung devised a subcommittee of the party politburo to help him take the most important political and military decisions. The subcommittee had five members, so it became known as the Committee of Five.
Initially, the Committee of Five consisted of Kim Il-sung himself, his son Kim Jong-il, and three other senior party figures.
Note. Kim Il-sung was North Korea's first ruler, and the father of Kim Jong-il. The idea of a Committee of Five is very plausible. A key to the personal power of a totalitarian dictator is "divide and rule." One aspect of divide-and-rule is the compartmentalization of information and responsibilities, so as to minimize the number of people that have an overview of everything.
