Secret Afghanistan files: revealed for the first time
The extraordinary leak made public by whistleblowers’ website Wikileaks has lifted the lid on more than 90,000 US military documents involving classified information direct from the battlefield in Afghanistan. It is the US army’s secret war diary – 200,000 pages of it – written by soldiers on the frontline.

The release of this set of documents have already been likened to the Pentagon Papers, which forecasted the demise of the Vietnam War, especially since it also demonstrates how the military has deliberately misled the public on many issues of the war including civilian casualties.
