Good survey of western history, doubtful, and it shore don't line up with the WT's spin...I've thought those very same things and wondered how any semi-educated JW could go along with such clear incongruity b/w the WT's version of history and the secular consensus. I think "semi-educated" is the key word, however. Most JWs I know quit history as an optional subject in school as soon as they can OR (and, sadly, this is more common), history is just not taught well in many schools. And few JW read much in the way of non-theocratic stuff; when they do, it's stuff that is either trivial fluff or that ratifies their beliefs.
I suppose I shouldn't generalize like that, but I'm basing it on my own experience. The historical discrepancies you point out so well came to light for me when I began to "wake up" and began seriously researching these very subjects. Ironically, I went back to university to finish my degree around the same time and that kind of critical thinking and reading to which I was exposed helped the process along. That, I believe, this the real reason the WT forbids higher ed.
In particular, your observation about the Anglo-American WP is salient, especially in view of the upcoming DC talk that supposedly will discuss this. Sure this last (7th?) king will only last a short while, depending on how you define "short"! Ha! Uncle Sam's sinking fast; Britain is already nearly inconsequential in terms of international clout and the US, while still a WP, is clinging to dominance with its toenails as all around it, other nations are catching up and surpassing it in terms of economic influence and power.
