"..it would be of the greatest possible assistance to the Dublin authorities in dealing with him since it would practically eliminate the risk of him being treated as a patriotic martyr…."

That's interesting seeing as Russell didn't die until 1940 ,a year after the letter is dated .It wouldn't actually have been a smear had the information about him being a communist agent been accurate. It's strange that he is now reviled for being a fascist in the same media that demonized him as a communist in the thirties .Russell was neither a fascist nor a communist.
