At a lunchtime reception for the diplomatic corps in Washington, given the day before the inauguration of Barack Obama as president, I was approached by a good-looking man who extended his hand. 'We once met many years ago,' he said. 'And you knew and befriended my father.' My mind emptied, as so often happens on such occasions. I had to inform him that he had the advantage of me. 'My name is Hector Timerman. I am the ambassador of Argentina.' In my above album of things that seem to make life pointful and worthwhile, and that even occasionally suggest, in Dr. King's phrase as often cited by President Obama, that there could be a long arc in the moral universe that slowly, eventually bends toward justice, this would constitute an exceptional entry. It was also something more than a nudge to my memory. There was a time when the name of Jacobo Timerman, the kidnapped and tortured editor of the newspaper in Buenos Aires, was a talismanic one. The mere mention of it was enough to elicit moans of obscene pleasure from every fascist south of the Rio Grande: finally in Argentina there was a strict 'New Order' that would stamp hard upon the international Communist-Jewish collusion. A little later, the mention of Timerman's case was enough to derail the nomination of Ronald Reagan's first nominee as undersecretary for human rights; a man who didn't seem to have grasped the point that neo-Nazism was a problem for American values. And Timerman's memoir, , was the book above all that clothed in living, hurting flesh the necessarily abstract idea of the : the disappeared one or, to invest it with the more sinister and grisly past participle with which it came into the world, the one who has 'disappeared.' In the nuances of that past participle, many, many people vanished into a void that is still unimaginable. It became one of the keywords, along with or 'death squads,' of another arc, this time of radical evil, that spanned a whole subcontinent. Do you know why General Jorge Rafael Videla of Argentina was eventually sentenced? Well, do you? Because he sold the children of the tortured rape victims who were held in his private prison. I could italicize every second word in that last sentence without making it any more heart-stopping. And this subhuman character was boasted of, as a personal friend and genial host, even he had been removed from the office he had defiled, by none other than Henry Kissinger. So there was an almost hygienic effect in meeting, in a new Washington, as an envoy of an elected government, the son of the brave man who had both survived and exposed the Videla tyranny.
