Former Top Iraq Commander Calls For Truth Commission

In doing so, Sanchez became the first senior military officer from the Iraqi theater to call for a truth commission. His position is particularly noteworthy because Abu Ghraib occurred on his watch, and he's been widely blamed for the abuses. He has said that his career was a casualty of Abu Ghraib. "That's the key reason, the sole reason, I was forced to retire," he has said.

Sanchez also fought back against Dick Cheney's claim that torture helped stop terrorist attacks: "During my time in Iraq there was not one instance of actionable intelligence that came out of these interrogation techniques."

Speaking to Huffpo after the event, Sanchez elaborated: "For the American people to really know what happened...this was an institutional failure, a personal failure on the part of many." He continued: "If we do not find out what happened then we are doomed to repeat it."

The event was organized by the Culture Project, and was moderated by MSNBC's Rachel Maddow.
