I've noticed a few things from all the news footage available of Kim Jong-Il:
1. Kim is generally doing one of three things: pointing/gesturing at something, watch someone pointing/gesturing at something, or clapping. Never speaking, never doing something actually interesting.
2. People in North Korea LOVE clapping for some reason. All the political footage involving Kim tends to involve a shitload of clapping. If the leader is clapping at something, everyone else is that's for sure. Maybe everyone's really happy over there?
Either the guy has never bothered to speak on camera, or the regime was afraid he'd say something stupid.
