Civil War (2024) it follows 2 journalists that are reporting on a modern Civil War in the USA. Not real partisan. Mostly about the brutality of it all
I didn't understand why Texas allies with California, tho.
My theory is that the writers didn't want to make it too partisan and didnt want to provide a blueprint for something that could actually happen
Plus I think if only 2 or 3 states were going to leave violently, those would have to be the ones. Every other state is too small.
