Great analysis of why there is interest by our government in UAP. I remain unclear however as to why the owners of UAP would have any interest in involving themselves with humans, especially not through initiating war or conflict with them.
Why would they engage when they can research us and our livestock as they wish and collect our genetic material at will, prevent us from using nuclear weapons, and stealth mine our Earth for all the materials they need?
I can understand the US military trying to shoot UAP down so they can access more advanced technology, and use it in offensive and defensive warfare. That is how human, mostly male-dominated, governments think - not how can we use this technology to help our species as a whole advance.
I am of the belief that as above so below.. There will be the good, the bad and the ugly amongst the UAP, and we have to realize there isn't anything we can do to stop them. Game over, Check mate.
