Following the warning of 3 retired generals, another warning on America's second civil war by CIA adviser, Barbara F. Walter, a political science professor at the University of California at San Diego, has served on an advisory panel run by the Central Intelligence Agency.

"...Walter, who has been studying civil wars and conflicts in places like Northern Ireland, Ethiopia, and Syria for the last three decades, applied international research and the metrics used to evaluate democracies in other countries to America. What she found was that the nation is “closer to civil war than any of us would like to believe,” according to a passage from the book published by the Washington Post.

The two best predictors of whether violence is likely to break out are based on if a country is an anocracy and if “ethnic entrepreneurs have emerged in a country that are using racial, religious, or ethnic divisions to try to gain political power,” Walter said on CNN. She described an anocracy as a “fancy term for a partial democracy.”

“The amazing thing about the United States is that both of these factors currently exist,” Walter continued. “And they have emerged at a surprisingly fast rate.”"
