Historian John Earl Haynes, who studied the Venona decryptions extensively, challenged Herman's efforts to rehabilitate McCarthy, arguing that McCarthy's attempts to "make anti-communism a partisan weapon" actually "threatened [the post-War] anti-Communist consensus", thereby ultimately harming anti-Communist efforts more than helping them. Haynes concluded that, of the 159 people who were identified on lists used or referenced by McCarthy, evidence only substantially proved that nine of them had aided Soviet espionage efforts—while several hundred Soviet spies were actually known based on Venona and other evidence, most were never named by McCarthy. Haynes' own view was that a number of those accused on McCarthy's lists above, perhaps a majority, likely posed some form of possible security risk, but a significant minority of others likely did not, and several were indisputably no risk at all.
