Bush Isn't Changing

“Make no mistake about it, I understand how tough it is [in Iraq], sir. I talk to the families [of those who have died]. I also believe we’re going to succeed. I believe we’ll prevail. One way to assure failure is just to quit, is not to adjust, and say it’s just not worth it. If we were to fail, that failed policy will come to hurt generations of Americans in the future.”- George W. Bush

“One way to assure failure is just to quit, is not to adjust, and say it’s just not worth it”? This isn't a football game. It's ok to "quit" killing people.

“I believe we’ll prevail. [About his talk with Tony Blair...] We agree that victory in Iraq is important.”- George W. Bush

What does victory mean here? How many dead people?
