Today, only 2 percent of the people know the name of someone serving in uniform. That means 2 percent of your listeners can actually conjure up the image of someone wearing the uniform of the military of the United States.

There's the assumption being made by the national security advisers to the Obama administration that the North Korean leadership is not suicidal, that they know they will be obliterated if they attacked the United States. But I would point that everything in South Korea and Japan is well within range of what they might want to do.

We've been in the nation-building business since World War I, and especially since WWII. The goal is not a Jeffersonian Democracy in Afghanistan, but a representative government that respects human rights, protects its own people, and is a friend of the West. These are very realistic - and necessary - goals.

I think as a rifle platoon and company commander your view is about 1,000 meters in front of you and you hope you can cover that ground and not have to back up and give it up again.

People come to me with their passion about transportation, about education, about health care, about agriculture, the dairy industry, the almond growers. I'm just a kid in a candy store, learning and eating up all this different knowledge.

Sometimes people ask me how difficult the astronaut program was, but being in Sierra Leone, being responsible for the health of more than 200 people, seven days a week, 24 hours a day, 365 days a year, at age 26 - that prepared me to take on a lot of different challenges.

I think mental illness or madness can be an escape also. People don't develop a mental illness because they are in the happiest of situations, usually. One doctor observed that it was rare when people were rich to become schizophrenic. If they were poor or didn't have too much money, then it was more likely.
