A great presentation by Tabletmag.com, detailing why some form of civil war, or at least a breakdown will occur in America. The basic argument is that two cultures have developed, which are now incompatible with each other; it is no longer the North and South, but localists or nationalists versus the globalist leftist elites. The takeaway is that there is nothing sacred about having 50 states in a nation, and that a smaller, more streamlined nation, with homogenous values would have greater social cohesion, and hence be ultimately stronger.
