Did Aliens Prevent Nuclear War?

Former NASA astronaut, Edgar Mitchell, the sixth man to walk on the moon, has made a startling claim that peace-loving extraterrestrials prevented nuclear war between the United States and the former Soviet Union during the Cold War. He said that there were a number of reports of UFO sightings as well as significant interference at nuclear missle sites during the UFO sightings. He went on to say that some nuclear weapons were actually disabled by the UFOs. Mitchell was an astronaut during the Apollo 14 mission in 1971.
