What's he gonna do to me? I live in a town of only 25,000. I could raise a company of armed men and women in a day. He's going to have to nuke all of us, and then he'll be lord of the dead.
He might make a demostration by nuking your town and then seeing if anyone else wants to disobey. It would be like dropping a couple of nukes on Japan and then giving them an ultimatum to surrender in ww2. As tough as the japanese were, they surrendered.
