Vyacheslav Molotov was a man of outstanding ability and cold-blooded ruthlessness. He had survived the fearful hazards and ordeals to which all the Bolshevik leaders had been subjected...He had lived and thrived in a society where every-varying intrigue was accompanied by the constant menace of personal liquidation.

He was above all men fitted to be the agent and instrument of the policy of an incalculable machine. I have only met him on equal terms, in parleys where sometimes a strain of humour appeared, or at banquets where he genially proposed...conventional and meaningless toasts. I have never seen a human being who more perfectly represented the modern conception of a robot.
