Actually, I have. Nukes differ from machine guns in a key aspect - they are risky to the passerby when just sitting on a shelf. The materials are radioactive, and therefore passively harmful and risky, even if the bomb isn't triggered. So, unlike a machine gun or hand grenade, someone who is simply sitting next to a nuke can be harmed. This gives society a legitimate interest in regulating nukes that does not exist for any firearm, even fully automatic ones.

Betcha didn't think I could defend that, huh? You don't know me very well.

I would like to point out for you Bushies, GW has folded on the assault rifle ban renewal, and is therefore no different then Kerry on this issue.
