I recently read HOW CIVIL WARS START by Barbara Walter. I saw this book seemed to have a similar premise, so I wanted to compare. This book is largely a laundry list of all the things that the authors disagree with and that readers should be frightened of (namely China). Oddly, the "only thing" that can prevent the destruction of the US, according to the authors, is Federalism (states' rights). It's unclear to me how letting red states and blue states choose their paths will protect the US from China. The authors offer no link between the two, nor any citations to back up other assertions throughout the book. Sorry I spent the time reading.
