Ignoring that Chile's record under Pinochet was not all that, Argentina at the start of the 1970s was still a relatively rich country. As the author of that paper noted, had it simply continued its growth trend, Argentina now would be as wealthy a country as Spain or New Zealand. Was the breakdown of Argentine politics into the dirty war of the 1970s inevitable? I'd choose to say not. With different personalities in charge, things could have gone differently. One certainly does not have to go to the lengths of having Argentina conquered by the British Empire and anglicized to make the territory of Argentina a First World country, not that this would be a good strategy either.
