For those who haven't watched the video, he talks about using respiratory viruses such as flu or corona type viruses (that is what it sounds like he is saying at 3:30). The project is called FunVac.I remembered this today. If i am reading the date correctly and it's real, it was recorded 15 years ago. They discuss spreading a virus modifying a gene supposedly controlling religious beliefs.
Checking up on FunVac, I discovered that the video has been debunked as some of the images used are from 2010, which would be unlikely if it was from 2005. Here is one site debunking it or is trying to, but only using the image date as evidence that all the information is bunk _Debunked: FunVax, Pentagon Briefing on Removing the God Gene [Hoax]
But, making a video which can 'easily' be debunked is a clever way to stifle people's minds into thinking that such things are not taking place and that it is only conspiracy theories. It is clear from what is coming out from various leaks that they have been researching into bioweapons of all kinds. Evidence from the past has also shown how soldiers or innocent villages are commonly used as guinea pigs for bio warfare experiments.
