The former commander of U.S. forces in Afghanistan defended his record on Monday following the release of a trove of documents laying bare the war’s multiple failures.

Retired Gen. David Petraeus, who commanded U.S. forces from July 2010 to July 2011, told the Washington Examiner that the gains made during his tenure were “indisputable.” His statement follows the Washington Post’s publication of the Afghanistan Papers — thousands of pages of documents which show many officials had doubts about the war, despite publicly supporting it for nearly two decades.
