On Sunday (25 July) whistleblower website Wikileaks made public over 90,000 classified US military files on the war in Afghanistan, making it one of the biggest leaks in US history. The documents give a real time account of the conflict between January 2004 and December 2009 from the perspective of US personnel.  Amongst other things they reveal that coalition forces have killed hundreds of civilians in unreported incidents, that a secret “black” unit exists to kill or capture Taliban leaders without trial and that NATO officers fear Iranian and Pakistani intelligence are providing support for insurgents. The documents were released to the Guardian, New York Times and German magazine Der Spiegel for analysis several weeks ago and whilst Wikileaks did impose a publishing embargo until July 25, they did not influence how the news reports were formulated and did not reveal the source of the leak to the news organisations. The White House has not disputed the accuracy of the reports but “strongly condemned” the disclosure, believing that it could “threaten national security”.
