Cosmic Top Secret - Robert O. Dean

Robert Dean has stated that in 1964—SHAPE, Supreme Headquarters Allied Powers Europe, prepared a highly classified, limited-distribution document analysing the threat posed by UFOs to NATO, a document with the title "The Assessment: An Evaluation of a Possible Military Threat to NATO Forces in Europe”. Dean has said that he read this document while stationed at SHAPE in the mid-1960s while working in the SHAPE Operations Centre (SHOC). He has described the report as being more than 8 inches thick and full of sightings, alien encounters and even autopsies.[1]

Dean claimed the research was approved by NATO and exposed (at least internally) that Earth was inhabited by four alien species that looked like humans and were secretly interacting with us.[2]
