I will not comment on or confirm what are alleged to be stolen State Department cables. But I can say that the United States deeply regrets the disclosure of any information that was intended to be confidential, including private discussions between counterparts or our diplomats' personal assessments and observations.

We need to make it very clear - whether it's Russia, China, Iran or anybody else - the United States has much greater capacity. And we are not going to sit idly by and permit state actors to go after our information, our private-sector information or our public-sector information.

I served on the budget committee in the Senate, and I remember as vividly as if it were yesterday when we had a hearing in which Alan Greenspan came and justified increasing spending and cutting taxes, saying that we didn't really need to pay down the debt - outrageous in my view.

Part of diplomacy is to open different definitions of self-interest.

One person's fashion is another person's disaster.

I'm still amazed at how my mother emerged from her lonely early life as such an affectionate and levelheaded woman.

What [Barack Obama] and I did was to say clearly what we're doing, all the bluster, all of the sanctions, that are just imposed by the American government haven't had much impact.Let's see if we can put together an international coalition to really cripple Iran, and then maybe we can begin a negotiation, and that's what I did. It was difficult. We had to get China and Russia on board, and not just get them on board by signing a piece of paper.
