This indeed can be the case if humans awaken to the cause at this time and contribute their energies in requesting a divine solution for the problem of the interlopers in your midst. This was a twin psychic perception that is mixing the past with the future and that is why it is not only cryptic but has its negative tone as well as positivity. The sources of the visions here were seeing both the prior annihilation of humanity at the hands of the extraterrestrials as well as a future withdrawal to create a pause of considerable length. The prior annihilation has already occurred. The future pause through withdrawal has yet to come about but can if the aims of GetWisdom come to fruition, but it can be considered as encouragement that this was seen as a prophecy so long ago—that is because there is considerable energy behind the idea and things are moving towards that eventuality. It is still too soon to guarantee things will work out, but the potential is growing and that was being perceived long ago and went on record as best could be done through the psychic perceptions behind the writings you cite.
