Overall this is a good book for the information it provided. The problem is with the usual bias, though Lahore at least tries to convey a certain degree of neutrality (but fails in my opinion). It never ceases to amaze me how any action from the German side is portrayed as tactless, bellicose, bullying, arrogant to name a few.
At the end of the book Lafore writes the following sentence: "By now Serbia, Austria, Russia, France and even Great Britain hat begun military measures of one sort or another; Germany alone among the Powers concerned had not yet done so". The country blamed for the war was the only country holding back till the situation escalated to a point where it had to act. That doesn't sound like the aggressive militaristic state seeking world domination in my opinion.
That said, the only thing Germany could have done in the eyes of authors like Lafore would have been nothing. Remak used something along the lines of "to simply roll over" whenever there was a chance for disagreement. Anything else is proof of the militaristic nature of the German Empire!? One example for what I mean can be found on pages 119 to 120: "The bullying character of German diplomacy in the twenty years before 1914 played a role in deciding the terms on which the war was to be fought. (...). There was a general embitterment of international relations that resulted from German activities". Like what? England fighting the Boer War? Russia getting beaten by Japan in 1905? France breaking the Treaty of Madrid assimilating Morocco into its colonies violating German trade rights? Germany disturbing French, Russian, or British interests, decided on in secret treaties, without Germany having any knowledge of them? It seems Lahore, like many other authors, simply takes over a certain set of assumptions that were established shortly after the war. Then he views every action of the German Empire under these assumptions, rather than critically analyzing the correctness of them in the first place. Russia's, France's, England's, and Serbia's conduct in the last twenty years before the war can be easily viewed as bellicose, arrogant, bullying from the point of view of The Ottoman Empire, Austria-Hungary, Germany, Transvaal, China, Persia, and countless other subdued countries around the world. But then again that might be using the wrong set of assumptions.
Still, the book contains valuable information and I liked especially the comparison of the nation states of England, France, Germany and others to the special situation of Austria-Hungary Empire not fitting into this new model of what constitutes a country.
