200 times GNP? Unlikely. Jared Diamond's book by the same name? That's not very specific if you don't know the name of the book. Is it "Iceland’s ninth century agrarian collapse?" Also she uses million where she probably meant billion (the author is American and she addresses Americans, so American millions should be what she's using). Otherwise, if her facts are correct then it is a very interesting case. I'm particularly curious about the specifics of how they decided on the constitutional drafters.
