Islandia (1983: Doomsday)

Islandia, officially the National Republic of Florida, is a nation off the coast of Florida. It once controlled a large portion of South Florida, but lost all but Islandia in the Floridian Unification War to. It formally claims all of Florida, similar to what Taiwan once claimed of China, but in reality only controls Islandia.

Pre-Doomsday
Islandia was a micro-city in Miami-Dade County. Although it officially was a city, its population never rose above 20.
