I think that the MOAB can be safely classified as a WMD. There's nothing small about destroying everything a few hundred yards in every direction.

Also, the U.S. military has small tactical nukes that can be put inside Howitzer shells. Each mini-nuke is a warhead equivalent to a couple kilotons. They're meant for taking out tank platoons, although if they were ever used, all of America's allies would disappear in the blink of an eye.
