Our President let's us know that "he understands" how "tough it is" and how we are going "to prevail":

BUSH: In all due respect, I've been saying it a lot. I understand how tough it is. And I've been telling the American people how tough it is. And they know how tough it is. And the fundamental question is, do we have a plan to achieve our objective. Are we willing to change as the enemy has changed? And what the Baker-Hamilton study has done is it shows good ideas as to how to go forward. What our Pentagon is doing is figuring out ways to go forward, all aiming to achieve our objective.

Make no mistake about it, I understand how tough it is, sir. I talk to families who die [ed. note--what?]. I understand there's sectarian violence. I also understand that we're hunting down al Qaeda on a regular basis and we're bringing them to justice. I understand how hard our troops are working. I know how brave the men and women who wear the uniform are, and therefore, they'll have the full support of this government. I understand what long deployments mean to wives and husbands, and mothers and fathers, particularly as we come into a holiday season. I understand. And I have made it abundantly clear how tough it is.

I also believe we're going to succeed. I believe we'll prevail. Not only do I know how important it is to prevail, I believe we will prevail. I understand how hard it is to prevail. But I also want the American people to understand that if we were to fail -- and 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.

...

So, no, I appreciate your question. As you can tell, I feel strongly about making sure you understand that I understand it's tough. But I want you to know, sir, that I believe we'll prevail. I know we have to adjust to prevail, but I wouldn't have our troops in harm's way if I didn't believe that, one, it was important, and, two, we'll succeed. Thank you.
