I'm actually genuinely optimistic about the United States and what's possible in the United States. And when you're out here, you see Americans across racial and economic and socioeconomic lines working together. And you maybe get a little bit less cynical than when you sit in the seat of kind of the epicenter of it all.

There's no doubt that it's still a dangerous place, Afghanistan. The fortunate thing is that the United States was helping to provide security for Chairman Karzai. And it shows that the United States is committed to that regime.

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.

Sometimes people decide to write reports even though they haven't been to Guantanamo . And so I would just suggest that people look at some of the work that's been done by people who have been there. But that's not to say that we will not be very glad at the day that conditions permit the closure of Guantanamo and the trying of its inhabitants or for their release.

In light of 50 years of bondage of Eastern Europe, [invading the Soviet Union in 1948 to prevent it from acquiring nuclear weapons] was probably a reasonable thing to do.

There are some places that have had real quarrels with the United States' policies, but I think the country is very well-respected worldwide.

We are at war, and our security as a nation depends on winning that war.
