re: "Folks with half a brain know that empty chemical warheads are the best kind"
Sorry, Zimbler, but I'm going to side with OCU on this.
Oh, you're LITERALLY right, and if you're just trying to win a high school debate on definitions then you've got it in the bag. But your victory would be a hollow one once my army holding chemicals-and-no-warheads had obliterated your army holding warheads-and-no-chemicals -- and the city it was defending.
You don't NEED warheads to disperse mustard gas or serin. A couple of glass beakers and a steel drum will do the trick. A nutjob cult in Japan did just that on the Tokyo subway system a while back. Not a warhead to be found, but lots of dead bodies.
