Admiral Michael Mullen sits down with Al Jazeera's Josh Rushing for a one-on-one interview covering his years as Chairman of the Joint Chiefs of Staff under both George W. Bush and Barack Obama. Rushing presses him on the wars in Iraq and Afghanistan, asking what those conflicts actually accomplished and what they cost the military as an institution. Mullen argues that firepower alone cannot win a war, and that diplomacy and international partnership have to carry as much weight as troops and weapons in any real strategy. He also talks through the weight of command itself: the ethical calculations behind orders that send people into combat, and the responsibility of holding one of the most powerful military positions in the country under two very different presidents. The format stays simple, a single extended conversation with no reenactment or outside footage, letting Mullen's own account of two wars and two administrations carry the hour.
