There's nobody who's had a resume like [Hillary Clinton] that's run for president.

My deepest regret from my years in public service is the failure of the United States and the international community to act sooner to halt these crimes.

Foreign policy is now a huge field. It isn't just people who are studying political science. There are so many aspects to it in terms of understanding hard science for people who are studying climate change, or people who are interested in health policy or food security, or people who care about education.

the purpose of foreign policy is to persuade others to do what we want or, better yet, to want what we want.

If intelligence were a television set, it would be an early black-and-white model with poor reception, so that much of the picture was gray and the figures on the screen were snowy and indistinct. You could fiddle with the knobs all you wanted, but unless you were careful, what you would see often depended more on what you expected or hoped to see than on what was really there.

Bill Clinton valued my opinion and always made sure that my views were heard, and people knew that he wanted me to talk.

To put it mildly, the world is a mess.
