This Cliff fellow seems to be somewhat interesting. He apparently has a background in software engineering working with Prolog and Artificial Intelligence. His observations from previous videos are interesting in detecting patterns in the news and societally. He apparently has had some kind of prediction of "secret technology" being released roughly July/August 2021 which seems to perhaps be ultimately related to or is "UFO disclosure". He has in this video from Sunday moved the timeline up again to May based on the rapidity of releases and discussion by the military:
(IMPORTANT TO REMEMBER THAT THE "UFOs" in question are likely CAVERN WORLD in origin and I also believe "disclosure" is happening soon, but that it is going to be misrepresented and bent towards "extra"terrestrials instead of "INTRA"terrestrials as it should be and thus be another luciferian manipulation.)
