Nightmare

Stephen Marche will chill your blood.  An excerpt describing the steps to civil war:

To sum up: the US Congress is too paralyzed by anger to carry out even the most basic tasks of government. America’s legal system grows less legitimate by the day. Trust in government is in free fall. The president discredits the fbi, the Department of Justice, and the judicial system on a regular basis. Border guards place children in detention centres at the border. Antigovernment groups, some of which are armed militias, stand ready and prepared for a government collapse. All of this has already happened.
