Okay, I've read through the whole thing so far.

This is not rationalist fiction. This is standard war porn, paperback thriller stuff. Many many technical descriptions of guns, rockets, military vehicles, etc. Throughout the story there's never any real conflict, just the American military (with help from the rest of the world) steamrolling everything, and the denizens of Heaven and Hell admiring the American way of life. It was well-written enough to hold my attention like a can of Pringles would, but I don't feel enriched by reading it.
