Some time ago the CFR published a paper (which it did not endorse--something that Corsi, et al., can't be bothered to tell us because it might hurt book sales) that spoke of a North American Union. A co-author of the paper was some guy named Pastor, who's been speaking and writing of this for years and years.
Corsi, et al., realized that there's money to be made playing on the zenophobic fears of some conservatives (in Corsi's case, by learning from his time spent as a FReeper). So they created a conspiracy-angle. Now, there's no longer a think-tank pondering it, or an egg-head promoting it . . . but an active conspiracy between all branches of government (and most members of it) with this nefarious "outside force." In this fashion, a road project in Dallas/Ft. Worth and an inter-modal trans-shipment facility in Kansas City become much more than infrastructure improvement projects, but a direct assault on Mom, apple pie, and the American way of life.
But it makes for good book pimping material to the tinfoil brigades.
Everything else aside, since you are familiar with Robert Pastor, would you agree that his visions could be fatal to our sovereignty?
