Brig. Gen. Mark Kimmitt on Iraq: 'Winning will be determined in the years to come'

The United States has officially ended its eight-and-a-half year military campaign in Iraq. The completion of the mission was marked with flag lowering ceremony in Iraq Thursday. Defense Secretary Leon Panetta was in Baghdad for the ceremony. More than 4,400 American troops have lost their lives over the course of the mission.

Today on American Morning, retired Brig. Gen. Mark Kimmitt, who was the U.S. military spokesman during the initial Iraq invasion, talks about what the United States has achieved in this pivotal middle eastern nation. As Kimmitt tells Carol Costello, the mission's success "will be determined in the years to come."
