The Trilateral Commission is only a piece of the story, don't forget the Bildebergs or the Council on Foriegn Relations (CFR). Every President we've had in the US for the last 40 years has been a member of at least one of those three groups. And the "Shadow Government" - no discussion of the Illuminati would be meaningful without talking about the shadow government. It's not even considered a conspiracy theory or paranoia. It's a simple fact that these groups exist and exert a powerful influence over world events and political policies. The only one that's kind of secretive about their existence is the Bildebergs but their annual meetings are fairly high profile since there's usually a military presence guarding whatever site they choose and no media coverage is allowed.
If you don't think the world's top governments are run by wealthy industrialists then, what world are you referring to?
