What the USA has also obstensively said to North Korea:
"Dear Kim Jong-il:
Take Note. Your fraternal allies, of whom one in particular came to see you in Pyongyang and negotiate arms deals as part of your Axis of Evil, are lifeless carcasses thanks to United States Military Forces.
You can expect the same for you and your dynastic sons, Kim Jong-Nam and Kim Yong-Chol.
Your time is limited, get your affairs in order."
