Alabama.
Here's how:
>invading army comes to Alabama
>sees army of rednecks slowly advancing
>sees incoming moonshine bottles hurtling towards their heads
>turn around and go home
>"Screw it, they'll just f**k themselves over."
>Alabama wins war by default - only US state left intact
Problems?
EDIT: One could substitute "Alabama" for "Utah" - as an Australian man, I claim the right to be ignorant
