British troops advance during the battle of the Somme in this 1916 handout picture

Why does the assassination of Archduke Franz Ferdinand -- the event that lit the fuse of World War One 100 years ago Saturday -- still resonate so powerfully? Virtually nobody believes World War Three will be triggered by recent the military conflicts in Ukraine, Iraq or the China seas, yet many factors today mirror those that led to the catastrophe in Sarajevo on June 28, 1914.

The pace of globalization was almost as dramatic and confusing in 1914 as it is today. Fear of random terrorism was also widespread -- the black-hatted anarchist clutching a fizzing bomb was a cartoon cliché then just as the Islamic jihadist is today. Yet the crucial parallel may be the complacent certainty that economic interdependence and prosperity had made war inconceivable -- at least in Europe.

This view, broadly analogous to the modern factoid that there has never been a war between two countries with a MacDonald’s outlet, became so well established that, less than a year before the Great War broke out, the Economist reassured its readers with an editorial titled “War Becomes Impossible in Civilized World.”

“The powerful bonds of commercial interest between ourselves and Germany,” the Economist insisted, “have been immensely strengthened in recent years … removing Germany from the list of our possible foes.”

The real “Great Illusion,” of course, turned out to be the idea that economic self-interest made wars obsolete. Yet a variant of this naïve materialism has returned. It underlies, for example, the Western foreign policy that presents economic sanctions on Russia or Iran as a substitute for political compromise or military intervention.
