This book takes a brief look at the visitation of extraterrestrials since the explosion of our atomic weapons in WWII and the government silence and denial of their existence. Is there evidence that they are a threat to us here on Earth? Are they here to protect the universe and themselves from our spreading atomic destruction, and helping us control the use of atomic weapons here on Earth? Do we have evidence of their aggressive intentions? What do we know about the terrestrials? It appears the US Government has had live terrestrials in captivity for at least five years. What have they learned?
