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?

There's a tremendous loss of talent to businesses who cannot make room for their employees to attend to family responsibilities. It really amounts to corporate waste: They hire really talented women and then lose them because they can't find ways to keep them productive and content the minute they can't "lean in."

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.

I very much admire Sheryl Sandberg for what she has done. I really do. But Sandberg's narrative also implies: "Well, it's your fault if you couldn't make it." There is a certain injustice in that.

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.

In Sarajevo and in Syria, these are societies - in Bosnia, in Serbia, in Kosovo, in Syria - where ethnicities live side by side and intermarry for long periods of time until it becomes valuable to exploit the division. And yes, the division's there because you can always revert back to history, you can always inflame it, but it is manipulated for political ends.

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