“Imagine, if you will, someone who read only Reader’s 
  Digest between 1950 and 1970, and someone in the same 
  period who read only The Nation or The New Statesman.  
  Which reader would have been better informed about the 
  realities of Communism? The answer, I think, should give 
  us pause. Can it be that our enemies were right?”
