Ah - I think the wisdom of Blackadder is called for here:
The Causes of WWI
Baldrick: The thing is: The way I see it, these days there's a war on, right? and, ages ago, there wasn't a war on, right? So, there must have been a moment when there not being a war on went away, right? and there being a war on came along. So, what I want to know is: How did we get from the one case of affairs to the other case of affairs?
Edmund: Do you mean "Why did the war start?"
Baldrick: Yeah.
George: The war started because of the vile Hun and his villainous empire-building.
Edmund: George, the British Empire at present covers a quarter of the globe, while the German Empire consists of a small sausage factory in Tanganyika. I hardly think that we can be entirely absolved of blame on the imperialistic front.
George: Oh, no, sir, absolutely not. [aside, to Baldick] Mad as a bicycle!
Baldrick: I heard that it started when a bloke called Archie Duke shot an ostrich 'cause he was hungry.
Edmund: I think you mean it started when the Archduke of Austro-Hungary got shot.
Baldrick: Nah, there was definitely an ostrich involved, sir.
Edmund: Well, possibly. But the real reason for the whole thing was that it was too much effort not to have a war.
George: By Golly, this is interesting; I always loved history...
Edmund: You see, Baldrick, in order to prevent war in Europe, two superblocs developed: us, the French and the Russians on one side, and the Germans and Austro-Hungary on the other. The idea was to have two vast opposing armies, each acting as the other's deterrent. That way there could never be a war.
Baldrick: But this is a sort of a war, isn't it, sir?
Edmund: Yes, that's right. You see, there was a tiny flaw in the plan.
George: What was that, sir?
Edmund: It was bollocks.
Baldrick: So the poor old ostrich died for nothing.
