And being a civil war where the other side has access nuclear weapons, it will result in nuclear retaliation. When a crime on the scale of nuclear weapon deployment is committed, it has to be responded to with nuclear retaliation against the parties responsible. It's the problem with weapons like nuclear warheads that can wipe entire cities off the map in an instance, in that instance a million plus innocent people die and create ten million plus grief filled loved ones demanding swift revenge.

So if the CHUDs nuke the liberal cities, it will result in a nuclear carpet bombing of key rural areas and most of the southern United States. If it is the feds using nukes to put down some kind of successful left-wing uprising, it will result in at minimum Washington DC, Maryland, Virginia, and the Carolinas being wiped off the map in retaliation with a hundred or so nuclear weapons.
