Simon;
You must read The War that Ended Peace by Margaret MacMillan (she had previously written a wonderful book called Paris 1919 about the Versailles Treaty negotiations). In this latest book she writes about the period 1900 up to 1914 and its clear that the assassination in Sarajevo was just the last act in a rather long play. What struck me was the ample evidence that the people of Western Europe and not just Wilhelm, Franz Joseph and Nicholas, etc., had long been primed for a war. She has a chapter on the rise of general and popular militarism during that period. She points out that despite the anti-war rhetoric of the Second Internationale, the Socialists in France and Germany supported the War (Jaures' assassination didn't help). Its as if after a long period of Victorian stability people wanted change at all costs. As a prelude, people seem to forget during that period you had the Bosnian annexation, two Balkan wars, two "Morrocan Incidents" and the Russo-Japanese War. While some might see WWI as merely an attempt at Imperial expansion, in fact, there was fear in Austria-Hungary that the failure to go to war might doom the duel Kingdom. Also, it wasn't as if people went to war blythly ignoring its consequences. The dismal results were predicted in Russia by P. Durnovo in his famous memo to the Tsar, in Germany Moltke expressed his doubts (and early on so did Bethman) and in Austria-Hungary Tisza, the premier of Hungary, predicted potentially disasterous results. In fact, despite Wilhelm's optimistic hopes, the whole premise of th Schlieffen plan was to knock out France as quickly as possible so that troops could be sent to the Eastern front. I was struck by the seeming inevitability of the War, almost a deus ex machina quality as if people were not really in control of events as the whole ship of state slid under the waves. Ukraine anyone?
