I was surprised how open and unguarded the military was. I expected more scrutiny, more supervision from command.

I think objectivity is like this strange myth that people think you're supposed to achieve, but actually, the dirty little secret is that it's not attainable any more than pure justice is attainable by the courts.

I would never want to pass a law limiting freedom of speech, but that doesn't mean we have to condone statements that undermine basic national unity and respect. Imagine being asked to defend a country where some citizens say the man in the White House isn't their president. Or a major presidential contender accuses the commander in chief of not even being a U.S. citizen. Those kinds of statements erode trust in our democracy, and it's up to both parties to publicly reject them. We have to restore confidence that we are a nation that loves and believes in itself.

No matter how many people you kill, using a machine gun in battle is not a war crime because it does not cause unnecessary suffering; it simply performs its job horrifyingly well.

The most profound question is, "What would I risk dying for?" The natural answer is "for my family." But for most of history, we didn't live in families. We lived in small communities that gave us our sense of safety and place in the world, so the natural answer would be "for my people." The blessing and the tragedy of modern life is that we don't need our community to survive anymore. When we lose that idea, we lose a sense of who we are.

Right now, America doesn't ask us to do anything besides pay taxes. We don't even have to vote. But as psychologists will tell you, when you have to sacrifice for something, you value it more. What about national service for young people? Everybody between 18 and 24 could spend a year or two working for this country in some capacity. It'd be an amazing thing. And it would mix this country racially, culturally, economically.

Firemen don't talk about whether a burning warehouse is worth saving.
