moreover, the kaiser, the one guy who could have ended the build up to war with a couple of telegrams, chose not to.
instead, he chose to go to war. yes, he was bullied by his generals, and scared of losing face, and everything else, but he was an adult man who made a decision which ended up being one of the historically worst ones of all time.
germany believed that their hegemony over europe could only be assured by military power, when in reality, they would have gotten everything they wanted (and more) if they had stopped their military build up and stopped aggrandizing the rest of europe.
i guess it took 5 million dead germans and 50 million dead europeans and two world wars and 50 years to teach them that lesson, but, sometimes, it takes a little time to get the message across.
