I'm not rushing to any conclusion; however my conclusion will be based on peer-reviewed evidence I see presented.
I did come across the Brennan interview before, however, only extreme confirmation bias would make me see that as anything to do with the topic on hand. Here's a pretty good explanation of the CFR talk - https://www.metabunk.org/debunked-cia-director-admits-chemtrails-geoengineering-stratospheric-aerosol-injection.t7721/
Also, I did check out Dane Wigington's videos earlier. While he's a great speaker, his work is not peer-reviewed.
