By the time August rolls around there will be hundreds of books, thousands of articles, and millions of words spoken by mostly pompous people about who was responsible for starting World War I. The Brits were the first off the mark to blame the Germans. They would, wouldn’t they? Max Hastings, a very good English historian who affects upper-class mannerisms (his father was a tabloid hack) and has the most extraordinary accent in a desperate effort to show he’s a blueblood, was among the first to produce a book and place the blame where it doesn’t belong. Among the few who got it exactly right is Christopher Clark, whose The Sleepwalkers hit the proverbial nail you-know-where. The irony is that the sixteen million dead, the disappearance of the great royal dynasties and of the upper classes, and the birth of communism and Nazism could all have been avoided if a certain Joseph Caillaux had kept his pants on. Let me explain.
