Has anyone done a study of this material to prove or disprove McCarthy's claims? I.F. Stone and the Rosenbergs and Klaus Fuchs, so long defended vociferously by partisans of the Communists and their allies, have been absolutely condemned by the Venona intercepts.
What about McCarthy's claims? If McCarthy said 250, and post-analytical study showed only a handful, or maybe 30 or 40 spies at State, then a fair-minded person would have to say, well, McCarthy missed. But if it were 200 or 150 or 190, I'd be inclined to give it to him.
Senator John Tunney, D-Cal., has also been identified as a KGB source, by analysis of materials taken, with the Yeltsin Administration's permission, from KGB files in the 90's.
