I've never been in a place where winning has hurt the ability to do anything.

There has to be a reform within the government that is tangible, that we can actually measure and that we have confidence is going to provide some of the differences that I think are essential to our troops to be able to carry out their mission and to the longer- term interests of our country.

As individuals, we will be judged in our lives by the totality of our actions. Not one thing will stand out. And I think that's how we get judged by our colleagues and that's how we get judged by the good lord.

I saw the president make the tough calls in the Situation Room - and today, our troops in Iraq have finally come home so America can do some nation building here at home. That was the change that we believed in. That was the change we fought for. That was the change President Obama delivered.

I've not been to Afghanistan or - but what people are clearly pointing to is that it becomes more difficult to have it. You could do it. I think weather is a factor. The most important factor though is credibility and legitimacy. What I wanted earlier to say is what I think Senator [John] Kerry is pointing to, which is important, is the strategic review on whether to send more troops is only one piece of the puzzle, important piece.

Counting the numbers of troops is not going to define our success here.There is no military success, ultimately, to Afghanistan. The Afghans themselves are going to define what happens here. And we have to convince ourselves that we have a strategy in place that empowers them to do that and that is realistic in what our expectations are from them and on what schedule.

Our troops are the best in the world. I have absolute confidence in the ability of the troops who are here, or additional troops, to do their part.
