Actually, we don't hide our chemical weapons... And we're supposed to get rid of them by 2004. And according to this we've already gotten rid of all of our stockpiles of biological weapons not related to bio defense research. Yeah, I see the grey area in there too. Are there classified sites that are housing one or the other of these menaces? Hell if I know... But why would there be when we have such a large supply of nukes?

And hey, I'm no huge fan of ANY weapons, especially nukes, but unless every country on the globe follows the mantra of War Games ("the only winning move is not to play") then everyone needs to kinda hold on to what they have to protect their own interests. I don't like the concept, but completely disarming every nuke in the world and preventing anyone from building another one seems pretty unreasonable.
