3. The Earth governments: Paul Hellyer (Canada - Minister of Defence) believing and admitting existence of Ets,, Haim Eshed (Former Israeli space security chief) says extraterrestrials exist, or Navy 'Tic Tac" video.
How much disclosure about UFO do we need?
Do we expect Mr Biden to speak bout it and do the briefing. As we know human leaders are mind controlled, corrupted, and according to David Icke some with reptilians DNA so called humans. Do we really expect that they will leave their jobs, adamite of countless laying.
I am sure that mind controlled, corrupted, with reptilians DNA human leaders will not only disclose nothing about UFO, but will sing again agreement with their peers (bad ETS).
The good ETs were really thinking that mind controlled, corrupted, with reptilians DNA human leaders would not sign again agreement with bad ones. And if they do sign they will leave. That is, was a poor plan or idea.
And last but nor least, who are those good ETs that Mr Brown is talking to. The Galactic Federation, The Domain, Ashtar Command, some ET'S resistance members, others. Would all of them leave or just a part.
Do you think that the Bad ETs would gently leave after the big disclosure. They will put up a fight, and there will be a new flood like in a Noah's Ark.
It is not easy, but do you want a disclosure be a disclosure.
