There is indeed a shadow government (SG).
This SG does possess secret knowledge. The first aspect of this special knowledge, which makes it efficiently secret, is that the SG not only know that the mythologies are mythologies, but also know that they themselves create and use those mythologies to manipulate the credulous masses. They know Sandy Hook is a Shady Hoax.
Beyond that first broad level of division between the knowledgeable and the credulous, the secret knowledge is distinguished by the division of rulers into two irreconcilable factions. Beyond the sheep-pens of the believers in myths like terrorism, there exist two fundamentally opposed views of which way to steer history.
One elite, the humanists, the Platonic or Neoplatonic faction, is dedicated to steering the course of history away from rule through so-called "noble myths." The other, the Aristotelians and their heirs, is committed to strengthening the rule by staging events that seem pivotal and focusing media attention on those events, for the purpose of establishing a permanent, "feudal-like" Utopia of obedient, simple-minded folk ruled by a tenured neo-Aristotelian oligarchy.
But, I take it you want me to provide you with proof that even you can't refute? I would provide that only to those asking and aware of their ignorance, as I am. I'm certain that many of the most active members here are far from ready to learn anything significant that isn't approved material.
