It will be like the Bosnia civil war.
Which was exactly that. Rural vs. Urban.
Urban is totally dependent onrual for food. Once you get the urbanites past the city limits, they are lost.
There are divides even there.
The front lines will be our own front doors.
Should the lead start flying, you must be ready to kill your neighbor, the guy who delivers your mail, your fellow parishioners, your kid's teachers, possibly even family.
It ain't gonna be pretty or well organized. There are too many divides.
The war in Bosnia was probably more divided along ethnic lines. Spain’s civil war was more of an urban vs. rural conflict - and urban people don’t grow food.
