I think I agree, though it means that there IS some sort of "New World Order" shit going on, some groups with extremely long reaches pulling media/government fear-agenda blitzes like that with a common theme and/or enemy?
Isn't it partly base instinct nature, aggressive alpha-dog behaviours, wanting to show the world he is boss? We're don't really live in fear of nature any more, but our animal instincts have never really gone that far away. The pack mentality is easily observed, again a nature thing, the media doesn't create it, it just plays on it and knows how to work it. Same with inspiring leaders, good and evil, they know what to say to get people fired up. I can't see us ever changing, we'll always find an excuse to shoot and sometimes eat one another.
Out of that list you posted, it could be argued that the 1930s-1940s fear was sort of justified?
