With quite a few states offering petitions to secede from the union, the question arises as to how strong the states would be as individual nations. What if they all seceded and then declared war on each other? This hypothetical question generated some very involved scenarios at Quora. Here's just a short snippet:
First came a period of massive migration back to the homelands. Facing the newly invented discrimination that will be created many felt the need to go back to their own people. While the individual states retained all military assets they couldn't control the individuals who fight. A Texas Marine stationed in California, would not fight for California. A soldier in New York would not fight against their home in Virginia and a sailor in Houston would not fight against their home state of Florida. The warriors returned to their home states and the states had to re-consider that when they measured troop strength of their new nations. Ultimately, they measured troop strength by how much of the population would return home.
