"I was in Kabul a decade ago when WikiLeaks released a massive tranche of US government documents about the conflicts in Afghanistan, Iraq and Yemen. On the day of the release, I was arranging by phone to meet an American official... He was intensely interested and asked me what was known about the degree of classification of the files. When I told him, he said in a relieved tone: “No real secrets, then.” ...I asked him why he was so dismissive of the revelations that were causing such uproar in the world. He explained that the US government was not so naive that it did not realise that making these documents available to such a wide range of civilian and military officials meant that they were likely to leak. Any information really damaging to US security had been weeded out... he said: “We are not going to learn the biggest secrets from WikiLeaks because these have already been leaked by the White House, Pentagon or State Department.” ...However, it was the friendly US official and I who were being naive, forgetting that the real purpose of state secrecy is to enable governments to establish their own self-interested and often mendacious version of the truth by the careful selection of “facts” to be passed on to the public. They feel enraged by any revelation of what they really know, or by any alternative source of information. Such threats to their control of the news agenda must be suppressed where possible and, where not, those responsible must be pursued and punished."
