Behold a Pale Horse is a 1991 book by William Milton Cooper.
Written after Cooper had been a member of the US Naval Intelligence Briefing Team of the Commander in Chief of the United States Pacific Fleet, the book details many of Cooper's claims about the alleged influence of UFOs on US government agencies, the New World Order, the assassination of President John F. Kennedy, the alleged Apollo hoaxes and other topics.
Another claim made in the book pertains to his own death. William Cooper, seemingly paranoid, claimed that he would be shot to death on his own property. True to his "fate," he was gunned down in precisely this manner years after publishing the book and settling down in Arizona.
The title of the book alludes to a passage in the Bible, Revelation 6:8: "And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him."

Behold a Pale Horse is definitely not a book to curl up on the couch with on a Sunday afternoon. The topics William Cooper discusses will very likely keep you reading late into the night. There are two types of people in the world: those who want to know who exactly is controlling whom, and those who are more comfortable taking things at face value. What really disturbed me was the theory of the true intent of the government. Cooper's account of what the government is capable of in times of heightened alert is extremely relevant now. It is important to keep in mind that this book was published before the attack on the World Trade Center because the US is finding itself in exactly the position Cooper predicted. Whether or not you think you might agree with the information in this book, I recommend any book written by someone who was killed for the purpose of silencing him or her. Be an informed citizen and know what your government is capable of.

Retired Command Sergeant Major Robert O. Dean discussed the reality of the alien presence, government disclosure policies, and classified information gleaned from years of research and time spent serving at the Supreme Headquarters Operations Center (SHOC), the NATO war room.

Though Dean believes the universe is "crammed with intelligent life," he no longer speaks publicly on the extraterrestrial presence because, as he explained, people are not ready for the "theological implications." According to Dean, there is ample evidence to suggest that alien intelligences have not only visited our planet, but have genetically manipulated humanity, as well as established every major religion on Earth.

Dean also pointed out that "black government" agencies, like the MJ-12, actually do exist and seek to "control the reality of the massive extraterrestrial presence." He also shared the story of a rumored secret meeting between President Eisenhower and an alien being. Dean said the meeting did happen and there is a film of the event, which shows humanoid creatures exiting from a golden disc, to prove it.
