CALLER: Being a veteran yourself, Mr. McCain, how do you feel about going to war a third time?
MCCAIN: I thank you for the question because that keeps me awake at night. Because I know that as successful as I believe we will be, and I believe that the success will be fairly easy, we will still lose some American young men or women. And that's a great tragedy. But I also believe that these young men and women, as they go into war, are fully understanding that they will be possibly saving the lives of possibly millions of people, including possibly millions of their fellow citizens, because there is very little doubt that if Saddam Hussein acquired a nuclear weapon and the means to deliver it, that he would attack the United States of America.
