According to Dr. Michael Salla and many other experts in the field of ET research, for almost 70 years the US government has engaged in an extensive "official effort" of disinformation, intimidation and tampering with evidence in order to maintain a non-disclosure policy about extraterrestrial presence. Writes Dr. Salla: "Ever since I began to publish the early versions of the chapters in this book in January 2003 as "Study Papers" on my website, http://www.exopolitics.org, I have received a consistent stream of supportive letters encouraging my research, and unsolicited information from former government, military, intelligence employees confirming many of my hypotheses. This has given me hope that eventually full disclosure of the extraterrestrial presence on the planet will occur, since interest is high and so much information is now in the public arena. States Jim Marrs, author of Rule by Secrecy and Alien Agenda: "Michael Salla presents an astounding and eye-brow raising alterative history of the past 100 years. He postulates that since at least the 1930s every major war and policy decision has been in response to an undisclosed extraterrestrial presence on Earth.
