Three months after it published the “Collateral Murder” video, WikiLeaks on July 25, 2010 released a cache of secret U.S. documents on the war in Afghanistan. It revealed the suppression of civilian casualty figures, the existence of an elite U.S.-led death squad and the covert role of Pakistan in the conflict, among other revelations. The publication of the Afghan War Diaries helped set the U.S. government on a collision course with WikiLeaks founder Julian Assange that ultimately led to his arrest last month.
