I don't see another CW2, it will be far too messy. There is no 'north south' type split. Cities will be battlegrounds. Argentina 1970s, Northern Ireland 1970s, Bosnia 1990s are more likely. Hence DW1.
In order for a DW1 we need the military to step up the plate, take the initiative and govern the nation in the manner it sees best.
I don't mind a "national regeneration" movement along the lines of Franco's Spain or Argentina in the 1970s. The libertarian ideal is so bankrupt and exhausted that I would accept several years of a Franco-style solution to our ideological conflicts.
It's coming. If even a remnant of America is to regain her Freedom, I don't see how it can be avoided.
