John Kerry knows more about more subjects than an awful lot of people. But I think it's a very hard job [Secretary of State].

As a leader, you have to have the ability to assimilate new information and understand that there might be a different view.

If we have to use force, it is because we are America. We are the indispensable nation. We stand tall. We see further into the future.

We have a responsibility in our time, as others have had in theirs, not to be prisoners of history but to shape history, a responsibility to fill the role of path-finder, and to build with others a global network of purpose and law.

The interesting part is, that being the United States Secretary of State, most places I went didn't have a problem with me being a woman, because I was representing the United States.

Well I do think, when there are more women, that the tone of the conversation changes, and also the goals of the conversation change. But it doesn't mean that the whole world would be a lot better if it were totally run by women. If you think that, you've forgotten high school.

[John Kerry] actually stole my line because when I became Secretary of State, I said, 'I hope my heels will fill Warren Christopher's shoes.' So he reversed that.
