The concept of a behind-the-scenes “North American Union”—persistently advanced by Farah’s WorldNetDaily, the John Birch Society, CNN’s Lou Dobbs, presidential candidates Ron Paul and Tom Tancredo, and others—is closely tied to the anti-immigrant sentiment that has struck right-wing politics over the last few years. But it has taken on a life of its own, thanks to vivid imagery like “the plan to build a huge NAFTA Super Highway, four football-fields-wide, through the heart of the U.S.” that was alleged in detail by Jerome Corsi last year. Corsi even provided a now-iconic picture, taken from a transportation-industry lobbying group.

In the picture, it appears as if almost all of middle America has been blanketed by some kind of yellow dust originating from south of the border and traveling up Interstate 35 like a swarm of killer bees. The “NAFTA Superhighway” and the “North American Union” may be “the quintessential conspiracy theory for our time,” as the Boston Globe recently discussed.

But what if Corsi and friends are wrong? What if the yellow cloud surrounding I-35 isn’t an “invasion” from Mexico but an “invasion” of God? That, apparently, is the theory of the youth-oriented church activists profiled on yesterday’s “700 Club,” who are running “purity sieges” at clinics and porn shops, where they claim to be “moving angels and demons” by, for example, “setting free” an inebriated young man from “the desires to be with men” through the laying of hands at a gay bar.
