I think there's a certain literary qualitiy to the "for want of a nail" view of historical events, where seemingly insignificant things have disproportionate effects on the world. But those events only stand out because they're ironically unexpected. Wars start because of tectonically sized movements of economies and political factions so vast that one single bullet could only make them flinch a little, but that doesn't make as memorable a story.

Not as arrogant as claiming to blow up an entire philosophy based on a knee-jerk response to one quote taken out of context though…umuhright?

> A pissed off Serbian with a revolver could destroy civilizations.

Yes, but why was he pissed off? Nationalism had to be invented somewhere.
