Hey check is out, this guy hasn’t heard of Franz Ferdinand! /s

As to not be rude or dismissive: the assassination of Archduke Franz Ferdinand is generally credited with the start of World War I. The implication being that a world war has been started over a seemingly small event that had tumultuous consequences thereafter. The further implication being that we may already be past a Franz Ferdinand assassination type event and may be worryingly headlong into a path to large scale warfare once again.
