In the paranoid mind, the Illuminati succeeded in their goals, and have now infiltrated every government and every aspect of society. They are responsible for every evil and every unjust act that ever occurs anywhere; the fact that absolutely no evidence of their existence can be found only serves to make them stronger and more frightening. They are the demon in the closet, and will probably never disappear from the paranoid fantasy world of right-wing conspiracy theorists.
