joining us now is retired air force colonel randy larson.e is the former chairman of military strategy and operations at the national war college and he's a senior fellow at the homeland security policy institute at georgia washington university. colonel larson, thank you so much for coming in here today. >> good to be here. >> as someone who flew hundreds of combat missions, we are talking 400 or so and as a former intelligence officer, how do you rate this operation? >> well, i think most american public do not understand how incredibly successful this was. they watch movies and it's easy for bruce willis and all those folks to do it. this was real. there are so many things that can go wrong and everything i have seen so far, the planning, the execution was perfectly done, even when they had a helicopter have a mechanical problem, they took extra ones this time. not like the iranian rescue mission. >> let's talk about this mission because there's question about whether the primary mission was to kill or capture bin laden. john brenen seeme
