It's interesting, the origin of this quote is somewhat mysterious, a bit like the Protocols of Zion. It is claimed as hoax rather vehemently all over the internet, so I had to look into if there is anything to it - I've not found the exact origin, but Estace Mullins quoted it, and Myron Fagan said Israel Cohen himself described it to him. But it is unclear if the title is a book title, a chapter title from some book, an article title, or whether the text is quoted from a book by Cohen or an article, essay or pamphlet. Cohen was a prolific writer, and somewhat oddly, wikipedia only gives a partial list of his published works. I'm going to look more into this, but I'll drop some links from various sources where I found alternative info about the quote beyond the hoax screeching of wikipedia and others:

(edit: BTW for those reporting OP for "illegal content" the above link is the text from the image in print in the congressional record, as quoted from June 7th, 1957)
