still once again in control of afghanistan. when you think about that, what goes through your mind? >> well, i think there's some things to remember, important things to remember, wolf. first of all, we went there to go after the people who attacked america and to hold them accountable. we held bin laden accountable. we significantly degraded the al qaeda network. i would point to you the fact that no one has attacked the united states, and especially from that region, in 20 years. that's not an accident. that's the work of great professionals that are working together to make sure that they're tracking threat streams and sharing information with each other. that's a significant accomplishment. my goal, wolf, is to make sure that it doesn't happen in the future. that we stay focused on threats.
