Every country wants to conquer the world, not just Germany. Every political party dreams of leading a nation by the nose wherever they want to take it. Of course I prefer the American kind over the Muslim Brotherhood kind. And having some inside document doesn't count for much ... one should be forewarned based on past history, not on a possibly forged document (see Protocols of the Elders of Zion).
Politically speaking, as I pointed out before, the Europeans (not N Americans) have a unique problem of having a more or less land connection to the ME, and all those angry young men there. As long as immigration is under reasonable controls in N America, there isn't an existential threat, just an annoyance. Given the poor response of Europe to the immigrant crisis (yes, they are both refugees and job seekers) under the Schengen suicide pact ... I don't see Europe existing much longer, whether Britain stays in or not. What started as resistance to Soviet occupation of Afghanistan, is turning into a Europe ending event ;-(
Of course there will be appropriate suspension of civil liberties in N America, due to paranoia and political exploitation by R-wing politicians ... and that is bad enough.
