What? No they aren't, they're trying to establish protocols within which a general artificial intelligence can be safely created. Whether a general artificial intelligence should qualify as a weapon of mass destruction is a different argument, but it certainly doesn't qualify as one from a legal point of view, and if the SIAI safety/friendliness plan works, it shouldn't from a practical point of view either!

I'm not nearly so confident. The Powers That Be don't need to be all that reasonable about these things. Because of the bit about the Power.
I expect a security oriented government body would be able to come up with as many ways for creating a superintelligence to be illegal as MoR!Harry could find ways to weaponise Hufflepuffs. Calling it a WoMD would just be one of them.
