I have spent a lot of time thinking about your second question. The simple answer---somebody needs to do it. Sooner or later, it is real important that the job gets done regardless of the cost. And I want to be the person to do it. Lets just make an assumption that Iraq was stupid and one man's foible---and a bunch of people followed orders and did it--and a bunch of them died and a bunch got wounded and maimed--that isn't their/our faul. I think Afghanistan was worth doing--in order to do Afghanistan you have to have people willing to do Iraq. In order to do D-Day June 6 1941, you've got to be willing to do Iraq. And the awful truth, is that I would rather go into battle with my brothers than do just about anything else. When I went to Iraq--wehn I volunteered and begged to go, at a certain level I felt I was betraying a higher self and people--professors--who needed more--but it was beyond me. At yet another level, I have always felt that anyone can lead a good op---I always felt the best able to lead a bad one--
