It's April of 2021. Division in the U.S. has been worsening by the year. The republicans and democrats declare war on each other. How would such a civil way play out? The Rs would control most of the military machinery, probably the deciding factor. Ds would revert mostly to sabotage and make it very hard to maneuver and refuel after massive damage to infrastructure. Battles would probably become localized. The map would be redrawn by natural boundaries of terrain, water, natural resources with rubber-band borders for years. Rs would control most area. Ds would have enclaves taken by force or treaty. How long would it last? 4 years 3 months and 7 days minimum. Max about 15 years 10 months and 22 days. Who would win? Both sides would win some controlled territory and some areas will be disputed forever. What would become of you? Most likely I'll die of old age, but I'd do my best to end my days as a double agent or spy or assassin working against the Ds. Firearms or aircraft will be involved. I'm looking forward to it.
