I believe that the answer is...singing. If every American taped him or herself singing a song (preferably a love song, or at the very least a happy song -- no angry songs like Eminem or Limp Bizkit) and mailed it to North Korean Prime Minister Kim Jong-Il (or better yet, email it to him as an mp3!), the gesture would so overwhelm him with emotion that he would start weeping like the bride's mother at a wedding. He would then cease all attempts to build a nuclear arsenal and embrace democracy as the only truly viable form of government and... Well, come to think of it, maybe that's a bit idealistic. I don't know, maybe continued economic sanctions and significant pressure from the international community, China in particular, might be a better plan. But the singing might help, too, you never know.
