Does the recent video I was sent, which was produced by a prominent spiritual group, reflect an awakening to the truth of the alien agenda, or is this just a corrupted Disclosure Movement manipulation?

Unfortunately, although it sounds tantalizingly close to your teachings because it is warning about a looming extraterrestrial problem, it is not being done because they are seeing the light, that people are being duped and there is in grave danger from the ET presence. But rather, they are being given the warning as a prelude to disclosure so the coming out party can be presented as an answer for the extraterrestrial dilemma, as they frame it. So the story will be there are good ETs and bad ETs and humans need protection from the latter and must ally with the former to survive. And as you have been told, this will mean that humanity is doomed because people must be allowed choices, and if they choose to line up with the darkness we simply cannot help them. You are participating in a race against time to get the word out. As you know, it is more difficult to change minds and hearts once they have been made up and carved out beliefs about a circumstance. This is human nature and can sometimes work against you, but a fact of life and a factor here in the doability of saving humanity.
