The United States of North America (USNA) is a now defunct political union. It consisted of the old United States, Mexico, Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama.
Collapsed following the nuclear bombardment of the east and northwest coasts of the USA, forming the Radiation Wastes. Greater Deseret (Utah, the majority of Nevada and Arizona, and parts of Idaho, Colorado, New Mexico, Oregon, and Southern California) and the South Central American States (Honduras, Nicaragua, Costa Rica, and Panama) were formed after the collapse.
