He is looking to precipitate a crisis, a civil war, which will be the vehicle for his bringing about a communist revolution in America.
These "Civil War" things are kinda nice, if... you want to see your parents shot, or perhaps you would enjoy cleaning the blood from the walls of youe new home. Maybe you would enjoy camping out in the woods for a few years while everything around you is set aflame. How about a month or two without a Big Mac?
Get the idea? Civil wars are the bloodiest wars one can participate in. Still want th have one? The Civil War ain't gonna happen.
