On 26 July, Wikileaks released thousands of secret US military files on the war in Afghanistan. Cover-ups, a secret assassination unit and the killing of civilians are documented. In file after file, the brutalities echo the colonial past. From Malaya and Vietnam to Bloody Sunday and Basra, little has changed. The difference is that today there is an extraordinary way of knowing how faraway societies are routinely ravaged in our name. Wikileaks has acquired records of six years of civilian killing for both Afghanistan and Iraq, of which those published in the Guardian, Der Spiegel and the New York Times are a fraction.
