I think that every country presents its own particular challenges, different cultures, different histories, different religions, different people. And different ethnic make-ups in those countries present different challenges.

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.

The problem is, you have to look at Afghanistan also in a global context where we've canceled basically our missile defense system undercutting the Czech Republic in Poland. We've I think not dealt with Iran with the kind of resolve that would show that we understand the nature of that threat.

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.

Everybody knows they're on the Obama team: There isn't vice presidential vs. presidential division, there's not a generational pull. People have internalized that this is a real moment in history.

The fact is, Bush's war policy has failed. It's failed! Who better to say so than Jack Murtha?

You never let a serious crisis go to waste. And what I mean by that: it’s an opportunity to do things you think you could not do before.
