This is a wonderful book for anyone that wants to make sense of what has been going on for long around the world. Great research book.
I found this book unsatisfactorily casual and slap-happy for the work of putative been-there-done-that expert with such lengthy tenure in and around things ufological. Yet, by reading this, I did manage to concretize a philosophical system that has been emerging for years as I read one UFO book after another--while also reading widely in other things paranormal, as well as a spate of less abstract fields, such as history, science, linguistics, anthropology, and such. Let us posit that aliens (1) exist; (2) have the technology to visit remote star systems; and (3) took greatly enhanced interest in earth only when it developed weapons systems capable of either harming other civilizations (i.e., in combination with its rocket technology) or of destroying itself (which would constitute a crying shame from the viewpoint of fundamentally beneficent aliens who respect other sentient life forms). Keyhoe leads me to believe--amid his conspiratorial musings and his subtle hints at what was meant by what was really meant by what Mr. X thought that Mr. Y intended--that they are watching us and executing a hands-off policy until such time that we pose a direct, immediate danger to ourselves (this will occur long before we pose a direct and immediate danger to exocivilizations), at which time--Starfleet-style "Prime Directives" od non-interference notwithstanding--they will take whatever steps are necessary to ensure the harmonious continuation of our culture. Whether that means utterly conquering and enslaving us, or surreptitiously seizing control over certain key organs of our governments (possibly to include forging certain elements of the whole-earth government whose existence Einstein endorsed as a logical and necessary eventuality), or just providing cultural "guidance counselors," who can really say. It is indeed food for thought to ponder the likely--well, the possible--archetypal alien ethos and surmise what it might intend for us and why it should, or will, occur when the time requires it.
