We never used to blink at taking a leadership role in the world. And we understood leadership often required something other than drones and bombs. We accepted global leadership not just for humanitarian reasons, but also because it was in our own best interest. We knew we couldn't isolate ourselves from trouble. There was no place to hide.

We don't have to sit by and watch our meritocracy be replaced by a permanent aristocracy, and our democracy be undermined by dynastic wealth.

Liberals are concerned about the concentration of wealth because it almost inevitably leads to a concentration of power that undermines democracy.

There is a crisis of public morality. Instead of policing bedrooms, we ought to be doing a better job policing boardrooms.

One big, glaring difference I can think of between Iraq and Vietnam is the news coverage. During the Vietnam War era, you had TV coverage of the war saturating the airwaves every night, and that coverage wasn't put through a military filter at all.

Richard Nixon as a 12-year-old was given a portrait of Lincoln that he hung over his bed. Nixon also justified what would later be seen as abuses of power by comparing America in the Vietnam era to the country during the Civil War.

Running is a basic ingredient for your health, just as much as eating and sleeping, but going out for a run by yourself and taking a moment to think also creates a certain peace.

Jesus said, 'Blessed are the peacemakers.' And I think a lot of people don't understand that there's a difference between a peace lover and a peacemaker. Everybody loves peace, but wearing jewelry around your neck and saying 'I love peace' doesn't bring it.
