It's not very different from dossiers that (intelligence, financial, political) analysts write about different scenarios all the time. While the text does contain more emotional imagery and blog-style tag lines, you'll basically find the same content in many organizations' databases.

Personally I think there is at least some merit to the reasoning behind this specific scenario: the population of the West is beginning to reject the globalisation effects that have brought global peace but left many disadvantaged, while religious and ideological radicalism is sharply on the rise world-wide. As the intellectual level of discourse is declining, the influence of populist ideas is becoming ever greater. From a bird's eye perspective, it seems humanity overall is in the process of rejecting peace, science, and secularism in favor of short-sighted economic considerations and dubious promises.
