It's a really weird situation this one... totally out of nowhere and doesn't entirely make sense. If Kim Jong IS being honest in his intentions, I reckon there has to be more to the story. Either NK has simply completely run out of resources to continue as they are and he's finally made the sensible choice to engage with the world rather than go for broke... OR perhaps there have already been secret talks and he's been offered something, or given an ultimatum.
