The American Founding Fathers gave us courts, independent jurists. They left room for civil society, which meant that citizens could directly associate in order to bring pressure on their governments. And they gave us a free press. They understood that you might have in the presidency someone who wanted to arrogate power into themselves. And they believed that was dangerous, having just experienced King George. And so they built a balanced system.

I don't think that anybody could have predicted that these people would take an airplane and slam it into the World Trade Center, take another one and slam it into the Pentagon, that they would try to use an airplane as a missile.

I've always said as a political scientist that "culture" is what we use when we can't explain things. I think it's more about accessibility. Part of the problem is that this is an expensive game [golf]. I know in a couple of places where there are black members, and they come from pretty much the same socioeconomic level that the white members come from.

It's important to Russia to be able to attract capital and to attract technology to develop their oil fields, their oil and gas fields, many of which suffer from lack of access to the very best technologies. And it's also important, and this has been the US government's view to have diversification of supply, diversification of supply roots and, of course, diversification in terms of alternative energy.

I studied piano from the age of three. My grandmother taught piano. I stayed at her house during the day while my parents worked. I obviously wanted to learn to play. And so she asked if she could teach me, and my mother said don't you think she's too young. My grandmother apparently said no. So I could read music before I could read, and I really don't remember learning to read music. So for me it's like a native language. When I look at a sheet of music, it just makes sense.

When you're in government, of course, you have protection and you have people who are looking out for your wellbeing, but you can't live in a state of fear. If you do, you're not going to do your job very well and you're going to give yourself high blood pressure, which probably isn't worth it.

Multilateral diplomacy is hard. It's slower, it's tougher, it's a bigger slog. I've learned that sometimes the things you'd most like to do something about, you really have difficulty unless the international community really mobilizes.
