In foreign policy, even if you hold high office, you can't be sure what the effects will be of the things you do.

A man has to define himself as a breadwinner, as opposed to thinking that well, women used to be caregivers who also wanted to have careers; men have always had careers, so why shouldn't they also want much more family time?

Young men keep telling me they don't 'have it all' either. And they may have a point. But if you define 'having it all' as the opportunity to have a successful career and a family, I'd say this. When a man tells his coworkers he's going to have a child, no one asks him how he'll manage or if he'll be coming back to work.

My husband has spent more time with our children than I have. I don't think they're better or worse off.

When we talk about gender pay gaps in the United States, and if you look at women without children, they earn 96 cents for every dollar that a man is earning, while for mothers it is about 76 cents. That's nearly 25 percent less. For single mothers, the situation is even worse. One third of them are living in poverty or just on the edge of poverty. This is an unacceptable situation.

I think an awful lot of the reasons people put forward for not liking Hillary Clinton play into deep-seated, negative female stereotypes: ambition, secrecy, calculating. I mean, that is Lady Macbeth, a kind of cold woman. I don't think that's Hillary. And I don't think people would judge a man in the same way.

I'm a child of the Cold War. You do not say, "Oh, my God, there are Russian planes, so I'm going to cede the field." I mean, what kind of world would we have had if the United States had done that for 60 years?
