You’ve got to believe in what you’re doing. If you don’t believe in what you’re doing, you’re not going to do it well. You truly have to believe in it. You have to believe that you’re doing what’s right. And I don’t think I could go to war — I mean I don’t think ultimately I could serve my country — if I thought we were doing something wrong. I think I would get out, I would leave. You don’t have to stay, you have an alternative. It’s not like the German generals who tried to justify what they did at the Nuremberg trials by saying, “I was only doing my duty.” That’s not right, because you have higher duties. You have a duty to your moral code, whatever it might be. You’ve got to do what’s right.
