US Evangelical magazine predicts European invasion of America

The Philadelphia Trumpet, a magazine published by the Philadelphia Church of God, based in Edmond, Oklahoma, is claiming that increased German investment in Latin America places the US in greater danger than "Mahmoud Ahmadinejad, Osama bin Laden and Vladimir Putin combined". The magazine argues that the recent spate of investment builds on groundwork laid by Nazis who took refuge in Latin America, and that "Germany’s takeover of Latin America would put European forces directly on the southern border of the U.S. and present an ideal scenario for a full-scale invasion of America".

Now being grumpy at "Old Europe" is one thing, but this is really out there. I know one shouldn't draw conclusions based on what one Evangelical church is saying, but the question is: to what extent will this sort of extreme nativism catch on?
