I can't speak on most of the things you said there, I just do not know, nor do i have the interest to learn. Some scabs you just don't pick!
I do believe that a system is in place to make sure one guy doesn't get into office and fck up 50 years of work to keep his job for another 4 years.
It has to be there to ensure longterm things - like food, energy, medicine, education, agriculture, etc, are able to grow according to plan without some nutjob getting into office and creating problems that we cannot undo.
Sounds like JFK (threatening to disassemble the CIA and stop entry into vietnam) butted heads with this group. We know how that ended, and we know that every president since has done what has been asked of him.
And think about JFK... if he HAD ended the CIA, I bet we would be in WAY worse shape, resource wise, in the world TODAY. All the quiet ops in the 70s, 80s, and 90s which gave the US advantages - we would have NONE of that. And without the good work they do - would USSR have won the Colr War? Probably.
So would JFK had - incredibly - hurt 2007 America greatly by dismantling it? I think the answer is yes. This quiet group just "does its thing" and keeps the place running without us ever knowing.
Interesting, scary, and needed all at the same time!
