The United States, Latin America, Europe, The Middle East, India and China are all set for civil war. Some of that will be like the war fought between the North and the South in the (somewhat less) United States during the 1800s. But, most of it will be social upheaval, ethnic strife and general stupidity.
It’s bad now, but when economic difficulty sets in… it will become catastrophic. Nothing turns a man or woman violent like hungry children. And, when the rule of law finally collapses, those without children will turn violent when others have something that they do not have.
