re: #162 Occasional Reader

Buenos Aires was also a strange choice for a first-strike by the bugs. “Foolish humans! Without tango, they’ll be helpless! Bwaaahahahaa!”

It was done to make the original book’s point that the USA had expanded to a world government — except that Heinlein’s protagonist was not Argentinian, he was Filipino. The filmmakers switched it to Argentina so that they could cast white kids in the main roles.
