Essentially it boils down to this: If someone breaks into your home, you can reliably combat the intruder with a firearm - without harming a bystander. If someone is attacking your town or village, you can at least situationally combat them with precision-guided munitions without killing any civilians (not that they are used ethically in all cases, just speaking to their potential use). Neither of those things is true of WMDs. You have to stretch the bounds of realism pretty far before you can find a way to deploy a nuke effectively without killing innocent people, or yourself.
