After going to the source, I still can't really tell if the Bush reference was intended to jab at the grossly-overused Obamite excuse, or if it was sincere. Maybe a mixture of both, with a confused bit of writing trying to masquerade as nuance.
Well, no matter. I'm not gonna drop ten bucks to watch some big downer, I've got at least a dozen SF books in my library with equally drastic apocalyptica in them, but better lasting entertainment value and mostly with good endings.
