When HuffPost asked Mitchell if he had told The Mirror that peace-loving aliens came to Earth to stop a nuclear war, that aliens were interested in our atomic weapons testing areas, and that ETs attempted to keep us from going to war and help create peace on Earth, he said, simply, "None of those statements were originated by me."
Notice that this is not an out-and-out denial that alien life exists, but that he simply does not believe they are interdicting military, nuclear and missile activity.
Lest you think that Mitchell is the only person with a public/governmental background to have gone over the edge in believing that ETs are here and among us, consider Canada's contribution:
Paul Hellyer was Canada's minister of defense during the 1960s. After his retirement, he became the first cabinet-level politician from a G8 country to go on record claiming that aliens are already on Earth.
Of course the angle I am looking at is when will the NESARAites/Lord Rama/Sherry Shriner and whoever else is overdosing on ETs are going to start trying to milk this for whatever it is worth?
