Besides continued diplomacy with potential allies who maybe won't just sign angry letters and sternly wag their fingers at a camera if/when we get invaded...

What else can we do with a tiny population and a dwarfed by our enemies military budget?

Nukes, anyone?

I'd like to hear some suggestions beyond "maybe we should do...something...idk what."

I mean besides sabotage after the fact, that's a given and I'm read up.
