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.

Motherhood is a greater predictor of wage inequality than gender is. It's enormous.

Our approach [to global security] has changed by the way we've elevated development. The biggest lesson is to recognize global responsibility.

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?

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.
