the war starting because civility broke down too much and americans started not seeing each other as one people
Broadly speaking, that's how every war starts. But I think this is far more fixated on "Imperialism returning to the core as fascism", with conversations about airstrikes on US cities and journalists getting gunned down as folks in between just kinda refuse to accept its happening.
You can definitely have a conversation about economics, but at some level the gears of war turn themselves.
This has the same energy as The Battle of Bull Run, which the Union did win in the end. The premise is that you've got a reporter rushing to the scene of a climactic final fight, not that the war is about to be over.
