Belka was once at war with many European nations. In order to protect itself seven nuclear bombs were exploded just inside the modern belkan border to halt the enemies advance. Since then the world has moved to ban all WMD's and the effects can still be felt in the seven southern of the eight regions in Belka bordering Prussia.
[this ties into the origins of my nation into the game it was based off of. I also suppose WMD's r banned here ike most regions, if for some reason they r allowed then I will delete this]
