According to Cooper, he served in the US Air Force and the US Navy and was discharged in 1975. He caused a sensation in UFOlogy circles when in 1988 he claimed to have seen secret documents while in the US Navy that referred to government knowledge and involvement with extraterrestrials.[4]
Cooper linked the Illuminati with his beliefs that extraterrestrials were secretly involved with the US government. According to Cooper, Dwight D. Eisenhower negotiated a treaty with extraterrestrials in 1954 and established an inner circle of Illuminati to manage relations with the aliens and keep their presence a secret from the general public. However Cooper believed the aliens actually "manipulated and/or ruled the human race through various secret societies, religions, magic, witchcraft, and the occult" and that even the Illuminati had become unknowingly manipulated by the aliens.
