I’ve read this and the article. The good thing about the article is that it contains the graphics. In one figure of FBI Silvermaster File Volume 15 the list of names contains Alger Hiss. He’s important in that he links this whole communism/subud plot to overthrow the US with the Carnegie Foundation, of which he was the President.
There was a very interesting commission in the House in 1953, The Reece Commission on Tax Exempt Foundations. These large tax-exempt foundations are run by the richest families in America. The Ford Foundation, the Carnegie Foundation, Rockefeller Foundation, Guggenheim Fellowship etc. The commission found that the organizations are actively working to undermine and change America into a collectivist society that can one day be merged with Russia. (Their words, not mine) By Russia, I presume they don’t literally mean Russia (at the time it was the only other superpower), but into a one world government.
