The United Commonwealth of America
The United Commonwealth of America (UCA), commonly known as the United Commonwealth (UC), Commonwealth, or in pre-1983 Contexts, New England, is a Country primarily located in North America. The 'Core' Commonwealth is bordered by Canada to the North and the Midwestern Union to the west. It is officially a federation of 14 states, two Canadian-American Joint territories, three "Sister Republics", a federal capital district, and several Indian Reservations. Although claiming 14 states, the country only controls 8, the other 6 being under the de-jure (and internationally recognized) control of the Western Rump State.
Following the collapse of the United States in the wake of the Three Mile Island incident, the remnants of the American government fled to the west coast, and little more than a year after the collapse, the New England states joined together and proclaimed the United Commonwealth, claiming the United States and her ideals of democracy had been betrayed, and that New England would carry the so called "Torch of Democracy". Soon after, the state governments of New York, as well as what was left of New Jersey and Pennsylvania would vote to join the Commonwealth.
The United Commonwealth is a member of the Tokyo Accords, an intergovernmental military alliance of 15 member states. The Accords are a direct successor to the North Atlantic Treaty Organization (NATO, Organisation du traité de l'Atlantique nord, OTAN). Much like NATO, the Accords are a collective security system: its independent member states agreeing to defend each other against attacks by third parties. Unlike NATO, however, the Accords also have a secondary function, officially known as the "Tokyo Treaty Anomaly Resolution Sector" (TTARS), often simply called the Tokyo Sector. The Tokyo Sector routinely publishes its findings, many of which controversial. Most of its members are sworn to secrecy, however the agency attempts to maintain an image of openness about the unexplained.
