"Kim's health is one of the most closely guarded secrets in the reclusive communist state. Kim, 67, was widely thought to have suffered a stroke last year, but there has never been official confirmation."
Kim Jong-il is about as dictatorial and guarded as they come. I'm wondering how any foreign intelligence source would get close enough to learn about Kim's health -- or about anything else that Kim didn't want known. Memeorandum has commentary.
