Lt. Gen. Michael Barbero, commander in charge of training Iraqi forces four years ago, says the United States was wrong to pull all of its troops out of the country with no residual force left behind. "We were wrong by not making a stronger case and insisting that we needed to stay in some numbers to continue to train, advise and develop this unfinished force," Barbero told NBC News. ISIS has eroded any confidence Barbero once had of the Iraqi troops— as the group continues to invade northern Iraq, they post videos of themselves driving American-made military vehicles and weapons they captured from abandoned military posts.
