What an interesting new thread, I am happy to participate.
There is a great book available which I unreservedly recommend: UFOs and Nukes - Extraordinary Encounters at Nuclear Weapons Sites, 2nd Edition, by Robert Hastings, 560 pages, with references, index and maps.
I have been a student of UFO phenomena off and on since 1965. In my humble opinion, the Phenomena, which has clearly made its presence known for many decades, cannot be relied upon to save us from nuclear war. I think that's our responsibility, and it may have to do with the notion of free will.
