Sauder details his decade of sifting through declassified documents and speaking with former insiders about their knowledge of these hidden installations. What he discovered will blow your mind. There is an extensive world that’s been built underground. A massive, experimental scientific and military infrastructure designed for very covert operations. With no public oversight, no budget limits and zero media exposure, these massive facilities exist in an entirely secret and world, operated by the most covert operators in the Deep State.
In the modern era, the advent of Deep Underground Military Bases (DUMBs) started with the Nazis, hiding their secret industrial base miles beneath the surface.
Sauder says that the US National Security State has dedicated massive Black Budget resources to the development of a sprawling network of secret underground command and control bases, ostensibly for the survival of humanity in a doomsday scenario and to set up Continuity of Government (COG) operations in the event of a nuclear war.
Beyond this mainstream explanation, there are reports of massive underground facilities designed to test advanced and exotic UFO technology obtained by crash retrieval teams with a secrecy ranking that is higher than those set for nuclear classification. Sauder posits that the motive for the massive secrecy surrounding the activities of this global network of deep underground bases is to protect reverse-engineered ET technology from prying eyes.
