My recommendations:

👉 Eustace Mullins book, "The Curse Of Canaan"
👉 Myron Fagan recording, "The Illuminati and the CFR Exposed"
👉 Janet Ossebaard video "Fall of the Cabal, Part 1-The birth of the Cabal." (and all her videos)
👉 Bill Cooper book & 1991 video, "Behold A Pale Horse"
👉 Phil Schneider lecture videos on DUMBs.
👉 Linda Paris videos at mcallistertvonline dot com

(books avail as audiobooks, on Youtube)

All are outstanding researchers or 1st hand witnesses or both.
Eustace Mullins book is outstanding detailed research, but overlooked the KMafia and Alien Agenda but he later recognized it. Ossebaard fills that gap on the Khazars beautifully. Cooper and Schneider had Security Clearance, where Cooper was US NAVY INTEL possibly with Q Clearance, and he witnessed UFOs first hand while in the NAVY. Fagan's recording spot on and very informative on the US History and meshes well with Mullins.

The overlaps actually help make sense of the Big Picture IMO.
