Query: Perloff is a bit of a nut!

Even though Mr. Perloff says that politicians using the "communist threat" is a bunch of BS, he is the consumate anti-communist who thinks that only the John Birch Society can save us! There is some info about the CFR that might be valuable, but it's difficult to know what might really be true and what is his personal opinion.It's OK as an intro to the CFR, but the author is still living in the early fifties.
