From George Will

[McCain said] Absent a commitment to send significantly more troops to Iraq, it would be "immoral" to keep asking the same number of troops "to risk life and limb so that we might delay our defeat for a few months or a year."

George Stephanopoulos: "President Bush has said he doesn't want to send more troops now. So by your own standards isn't it currently immoral to keep Marines and soldiers, other service people in Iraq?"

McCain: "Yes it is."

Moments later, Stephanopoulos asked: "At what point do you say, I am not going to be complicit with an immoral policy?"

McCain: "When I think we've exhausted every possibility to do what is necessary to succeed and not until then, because the consequences of failure are catastrophic. . . . We left Vietnam, it was over, we just had to heal the wounds of war. We leave this place, chaos in the region and they'll follow us home. So there's a great deal more at stake here in this conflict in my view. A lot more."
