McCarthy prove to be right....there were Soviet sympathizers in the Federal government, in the state department....over the years the evidence became revealed ...FBI recordings confirmed his suspicions...as did the Verona intercepts etc., 

It's rather amusing to see the reaction of so many in the establishment, the media and the Hollywood types , the useful fools that once harboured Soviet sympathies,  getting mugged by the very same NKVD/ KGB/ FSB  that they turned their blind eyes to in the past.
