McKenna saw more than Borah becoming an antique in his own time, she saw damage inflicted by his positions: "time was to demonstrate the utter bankruptcy of the narrow nationalistic policy which the irreconcilables decreed and to which the Harding, Coolidge, and Hoover administrations submitted with such disastrous results." Borah's comment regretting that he could not have talked to Hitler has been repeatedly cited as evidence of naiveté in those who believe in the power of pure diplomacy. Conservative commentator Charles Krauthammer referred to the statement in at least three of his columns, making an analogy to negotiating with China in 1989, with North Korea in 1994 and with Iran in 2006, and it was cited disparagingly in a 2006 speech by Secretary of Defense Donald Rumsfeld.
