America the Broken
I based this map on the "what if" scenario that Washington DC and the primary federal infrastructure were fissioned out of existence one day in the mid-'90s. Immediately after, the individual states would likely try to continue operating independently, but very quickly the uneven distribution of resources across the country would cause each region to start forming new joint governments with their neighbors. Existing borders would blur along the lines of supplies and major utilities, and natural borders would become more sustainable. It doesn't immediately turn into all out civil war. Trade, treaties, and annexation likely would be just as prevalent in the reshaping of the nation.
Feel free to ask me questions or tell me all the ways you think I'm crazy. I think I have decently valid reasons for the more extreme decisions, but I'd love to know why I'm wrong.
