"The novel's merit, then--or its offence, depending where you stood--was not that it was authentic, but that it was credible. The bad dream turned out to be one that a lot of people in the world were sharing, since it asked the same old question that we are asking ourselves fifty years later: How far can we go in the rightful defence of our Western values without abandoning them along the way? My fictional chief of the British Service--I called him Control--had no doubt of the answer: "I mean, you can't be less ruthless than the opposition simply because your government's policy is benevolent, can you now?" Today, the same man, with better teeth and hair and a much smarter suit, can be heard explaining away the catastrophic illegal war in Iraq, or justifying medieval torture techniques as the preferred means of interrogation in the twenty-first century, or defending the inalienable right of closet psychopaths to bear semi-automatic weapons, and the use of unmanned drones as a risk-free method of assassinating one's perceived enemies and anybody who has the bad luck to be standing near them. Or, as a loyal servant of his corporation, assuring us that smoking is harmless to the health of the Third World, and great banks are there to serve the public. What have I learned over the last fifty years? Come to think of it, not much. Just that the morals of the secret world are very like our own."
