that's a central argument going on right now. the tension between, you know, the right of congress to -- the obligation of congress to declare war and the president's position as commander in chief. there's always been this tension. it is being heightened now because of the present situation. >> you first, do you have any reason to believe that george w. bush had a clear notion of what we were doing in afghanistan in the first place?รง a clear notion. >> no. no. >> do you think he had a clear notion? >> no. i think aside from the osama bin laden approach, no. >> but he left the door open for that guy to escape to tore tora bora. >> look, there are a lot of reasons those things went down the way they did, but it doesn't go to the fundamental question, why are we there and what will it look like when we leave? >> we know one person has a deep gut commitment to the military. that's john mccain, who served in vietnam, paid his price of loyalty to the country in the worst way, like six years of torture over there. we know his instinct, to back the troops. the question is, are the troops being given the right orders?
