A new book entitled "The War That Ended Peace" by Margaret MacMillan is an in depth look at what was going on in Europe in the years preceding WW I. It has come out at an appropriate time, since it has been 100 years since the assassination. Some highlights: There were a whole series of crises in the preceding period where Europe was on the verge of war, but at the end someone backed down. Dogger Bank 1904 (Russia vs. Great Britain - minor), Morocco 1905 (Germany vs. France), Bosnia annexation 1908 (Austria-Hungary vs. Russia), Morocco 1911 (Germany vs. France), Balkan wars 1912-13 (many players). In addition there continuing tension between Great Britain and Germany because Germany decided it needed a big navy and G. B. felt threatened. Serbian expansion dreams concerned Aust.-Hung. particularly after the Balkan wars. Russia at the time decided it was Serbia's protector. There is a lot more. Anyone interested in the subject should read it. One criticism - at times the author throws in too much detail.
