Musing about the origin of WWI

From a "British History" column at the BBC:

lt was an act of regicide that catapulted Europe into war - an act that not unexpectedly took place in the Balkans. The region had been in a state of ferment for years, and the assassination of the heir to the Hapsburg Empire, the Archduke Franz Ferdinand, by a Serbian nationalist, was the culmination of a train of events leading inexorably to war.

Yet at first the monarchs of Europe did not take the incident too seriously. lt was expected that the Hapsburg Emperor, Franz Josef of Austria-Hungary, would demand and be given an apology from Serbia. By now, however, Europe's leading nations were locked in alliances - there was Serbia with Russia, Russia with France, France with Great Britain, Great Britain with Belgium on the one side, and Germany and Austria-Hungary on the other. With Serbia's apology not proving abject enough, relations between Serbia and Austria-Hungary were broken off. This finally alerted Europe's family of kings to the danger that threatened them.

As the alliances clicked inexorably into place, a positive snowstorm of telegrams between the crowned heads tried to avert the inevitable. Kaiser Wilhelm II (Willie) was particularly assiduous in keeping touch with his cousins Georgie and Nicky. But by now there was nothing they could do. Their constitutional powers counted for almost as little as their cousinhood. Although, technically, Franz Joseph, Nicholas II and Wilhelm II could perhaps have curtailed the coming hostilities, they were at the mercy of more powerful forces: the generals, the politicians, the arms manufacturers, and the relentless timetables of mobilisation. Ultimatum followed ultimatum. In the face of national pride, imperial expansion and military glory, the protestations of the crowned heads were swept aside. On such giant waves, they could only bob about like so many corks.
