Kennedy was significantly different than Eisenhower before him, and different from Johnson after him. So those three years were the beginning of a détente with the Soviet Union, a new feeling for peace, a seeking out of a new ally with the Soviet Union - the end of the Cold War, as Kennedy called it in his American University speech.

JFK was leading the world, leading the United States into a new position with the Soviet Union. He was calling for the end of the Cold War. He would have been reelected in 1964 because he was vastly popular.

I'm a history person; I love history. But I am conditioned by the present.

Now, we live in an age where we have so much information that we do tend to overload. The Greeks did too, though.

I don't agree with Bernie Sanders that the banks should be broken up at this point. But Hillary Clinton's acceptance of huge contributions from Goldman Sachs and others... And we don't debate what Clinton has done. She has a public record. She's been Secretary of State. She's basically a candidate of Wall Street, for Wall Street.

You're not a historian, but most historians will tell you that they make very discrete judgment as to what facts to omit in order to make their book into some shape, some length that can be managed.

When I'm working with another writer, I tend to make a lot of effort. When I collaborate with a writer, I'm not interested in credit, but I'm feeding him stuff all the time that I feel is important to shaping the script.
