The North American continent, and most likely the entire planet, is crisscrossed by deep, seemingly nearly indestructible tunnels that predate history.

I find this topic interesting. The Utes tell stories that their ancestors emerged from the earth.

Obviously the Deep State and their maniacs have access to the best science, of genetics, brainwashing, training, and basically all the knowledge of mankind, a lot of which is being held back to be used by said maniacs for their own purposes.

I think that's not an unfounded assertion.

As such, it is only logical that they have created a large "shadow army" of tailor-reproduced and brainwashed non-citizen military personnel.

It doesn't just logically follow that since the state has access to technology and knowledge that they have created a shadow army of millions who have lived their entire lives underground. Without you sharing how you know, it's really kinda non-information. I'd rather hear how you know and consider whether to believe it or not.
