thus, the schlieffen plan, formulated by the german general staff after the 1870–71 franco-prussian war, is a good example of centralized war planning and of jominian theory: everything was so rigidly planned that there was almost zero ability to adapt for sudden changes. when world war i started in august 1914, the military told the emperor that they could do nothing but invade france, although the emperor changed his mind, hoping that if he didn't invade france, great britain wouldn't enter the war (in virtue of the 1904 "entente cordiale" agreement). but the plan was too rigid and didn't allow for modification, thus potentially becoming one of the indirect causes of the war (although it surely wasn't the only one: delanda, who begins his book quoting fernand braudel, doesn't believe in unicausality or determinism).
