Assuming you have the time, you may starve the city into submission or 'poison the well'. But surely these have been considered?

I noted that you mention a severe allergy to nuclear weapons. I'm wondering if perhaps you will be somewhat less allergic to the nuke's ugly cousin?

There's only one way to find out! He's still out there, somewhere, supposedly - banned by treaty.

He'll make short work of Opella's population, and leave the city infrastructure completely intact (except the electronics, which may become slightly fried). Your army should be able to walk in there within a few weeks. Not even the cockroaches survive.
