This past June, Alan Rusbridger, the editor of The Guardian, phoned me and asked, mysteriously, whether I had any idea how to arrange a secure communication. Not really, I confessed. The Times doesn’t have encrypted phone lines, or a Cone of Silence. Well then, he said, he would try to speak circumspectly. In a roundabout way, he laid out an unusual proposition: an organization called WikiLeaks, a secretive cadre of antisecrecy vigilantes, had come into possession of a substantial amount of classified United States government communications. WikiLeaks’s leader, Julian Assange, an eccentric former computer hacker of Australian birth and no fixed residence, offered The Guardian half a million military dispatches from the battlefields of Afghanistan and Iraq. There might be more after that, including an immense bundle of confidential diplomatic cables. The Guardian suggested — to increase the impact as well as to share the labor of handling such a trove — that The New York Times be invited to share this exclusive bounty. The source agreed. Was I interested?
