Yeah, I'm not gonna go out of my way to defend the IP but he's talking to mostly uneducated, unskilled laborers that got picked up because they're young, relatively fit men. They're probably not a volunteer force, and don't have the training or equipment to march down a road and fuck shit up, as he says they ought to do.
He's right, though. Iraq had a shot at self-sufficiency and they let ISIS form right under their noses.
