I'm not personally fearful, but I look out, and there are a number of things that concern me, and I'm hopeful that we can overcome them.

I laugh almost everyday. I have a good sense of humor, so I'm always finding something funny.

The first Republican I knew was my father and he is still the Republican I most admire. He joined our party because the Democrats in Jim Crow Alabama of 1952 would not register him to vote. The Republicans did. My father has never forgotten that day, and neither have I.

My favorite quote is Thomas Jefferson`s "The God who gave us life gave us liberty at the same time." Well, he was a slave-owner. But these institutions, while they weren't perfect at the time, did allow people to prosper and to continue to struggle and build toward them. That's what you need, is good institutions and I think people will eventually live up to them.

Everywhere that I go in the world, people desperately look to American leadership in all of their world's most difficult problems. You can look at any region of the world and the United States is still the country to which those regions look for leadership.

I certainly have no regrets about overthrowing Saddam Hussein. I'd do it again. And, yes, there are a lot of things that I think we'd all do differently. Maybe we made some erroneous assumptions about the fabric of the society in Iraq and about the solidity of some of the institutions. And yes, there are a lot of things I would do differently. I'd probably work to rebuild Iraq from the outside in, rather than concentrating so much on Baghdad, for instance.

This is not 1968 and the invasion of Czechoslovakia, where Russia can threaten its neighbors, occupy a capital, overthrow a government, and get away with it. Things have changed.
