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.

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.

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.

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.

Obviously what I think Senator [John] Kerry was pointing to, which is absolutely correct, which is the essential part of the strategy or a key component or a leg on the stool, is an Afghan partner that is ready to take control of both the security situation in Afghanistan, and the civilian side of that.

As we move forward, I am looking for a new leader of the Chicago Police Department to address the problems at the very heart of the policing profession. The problem is sometimes referred to as "the thin blue line." The problem is other times referred to as "the code of silence." It is this tendency to ignore. It is the tendency to deny. It is the tendency, in some cases, to cover up the bad actions of a colleague or colleagues.

Rather than doing the kind of fact-checking that normally goes with a story, you ran with certain stories for not wanting to get beat. There's a pressure that exists in your profession. I would be surprised in any honest exchange that you say that doesn't exist.
