In 1968 the USSR and United States of America launch their plans for mutually assured nuclear destruction. Thankfully, the High Altitude Nuclear Defense Division (HANDD) had created nuclear shields in Cheyenne Mountain and Chicago.
Over the next several decades they warred to regain control over the former United States. By 2021 they are opposed only by the Mexican Republic in the south and the Continental Army, a scattered organization of revolutionaries located throughout the continent, but mainly in the midwest.
Point of Divergence
Nuclear States is a story made possible by alternate history. The events take place in a timeline parallel to our own, yet not our own at all. The point of divergence dates back to 1884 when Nicola Tesla first met Thomas Edison.
Unlike in our own timeline, Tesla and Edison immediately hit it off and became best friends. Edison used his expertise in business to secure funding for Tesla who invented many marvelous machines.
This ultimately led to the HANDD's ability to create the forcefields which protected Cheyenne Mountain and Chicago. The HANDD also made many more technological advancements.
