the fact that all the study and theory about Eurabia seem basically lifted from the same kind of study who predicted an italian overthrow of America a century ago is not a think who make me really confortable with the story.
It's amusing to see how history repeats : After a hundred years, we're once again living in a world saturated by that crap invasion literature genre (e. g. the one pre-WWI Brits and French used to adore). Well, by "crap" I mean, that the genre is crap as far as plausible human threats go, I'm not talking alien invasion stuff now.
