Just to scrape the tip of the disinformation iceberg...
do you have a solid knowledge of who FDR was and what he was all about ? That is, his business relationships over his whole career, not just his Presidential career, as well as his family background.
The perception of FDR that has been fed to Americans is a fantasy whitewash.
Antony Sutton was a great researcher. I have one of his books. However, Antony Sutton didn't believe in standard conspiracy theories and actually criticized them.
From 1977 to 1981 I was a member of the John Birch Society. I started out as gung-ho as you can imagine but I came to see some very ugly things about them. My experience has turned me off on conspiracy theories--especially those theories that blame "communism" on "banksters" and which advocate nationalization of the financial sector. I hope you will understand, even if you don't share, my concerns. I appreciate that you are not an anti-Semite.
