No Spain? - Wasn't Columbus, in the service of Spain, Cortes and Pizarro some of the worst warmongers in history? And what about Prussia and Nazi Germany; Julius Caeser (Rome); Leopold of Belgium; Genghis Khan and Attila the Hun? Do they all get a pass somehow?
I checked the source material of this aging quiz again and if I understood correctly, the Independent was referring to the most warmongering countries right now.
