Bad example though. A nuclear bomb would be akin to the bullet, which in this case, is designed to be lethal. The aircraft, or launch vehicle that delivers the payload, on the other hand, would be more like the gun.
However, let's run with your example for a moment. I believe fission and fusion are the words you were looking for in reference to a nuclear explosion. Now, let's see. Without fusion or fission, I believe not only are we left without nuclear weapons (which I happen to agree, we shouldn't need, except possibly to attempt to deflect an object in space bound for Earth), but we're also going to have to lose a multitude of power plants and all of the dependent synthesized radioactive materials used in the medical world. Well hell, since we obviously can't be trusted with it, neither can the rest of the universe, as, you know, there could be some aliens out there waiting to nuke us. So let's go ahead and ban that, universally. That means our sun, and every other star out there, is going to have to go too. Actually, since the atoms that make up your physical being once underwent such a process, why don't we ban them as well? I mean, we wouldn't want them lingering around either, just in case they end up being used to harm someone.
The next time you want to troll someone, reconsider. It's really not your forte.
