Especially when you read the earlier history of the in the US and Europe. It will amaze some who's names are associated with these groups over the years. Most of our Presidents and others highly placed in the Government (Congress, Executive and Judicial) as well as the military.
An interesting book published in 1962 was 'The Invisible Government' by Dan Smoot. He took a lifetime "beating" (figuratively) from writing it. Also some others were written by Gary Allen ('The Rockefeller File' and 'None Dare Call it Conspiracy') and the 'CFR Part II' by Pheobe Courtney. All these books are old but quite interesting.
Even Bubba Clinton's old Professor, Carroll Quigley, called 'Tragedy and Hope' discussing some of these issues. Theres is even one on nonprofit and such called 'Foundations: Their Power and Influence' by Rene A. Wormser.
The Conspiracy Archive is on-line at http://www.conspiracyarchive.com/ and has many writings on this subject. Probably many more sites to study the "conspiracy" and its more modern counterpart 'The Right Wing Conspiracy' made so popular by Bill and Hillary.
But I think you'll enjoy more the writings on 'One World Government' and the 'Globalist Conspiracy' that is debunked by so many liberals and Democrats today. Maybe even more compelling and interesting reading that the UFO's and Roswell theories and possibly all the theories regarding Mason's.
Yep, I always believe what liberals and dims tell me. lol
I've not heard of the link in your post.
