I think that we all know what evil is. We have a sense of what's evil, and certainly killing innocent people is evil. We're less sure about what is good. There's sort of good, good enough, could be better - but absolute good is a little harder to define.
As a leader, you have to have the ability to assimilate new information and understand that there might be a different view.
I was in Europe and it was at this stage that I fell in love with Americans in uniform. And I continue to have that love affair.
I didn't want to set up a women's studies program. I thought women should learn to operate in a coeducational atmosphere, because, especially in national security and international affairs, it's male-dominated.
If you look at U.S. history through religious history, there is very much a motif that shows the importance religion has played in the U.S. We're a very religious country and it affects the way we look at various political issues.
I really think that there was a great advantage in many ways to being a woman. I think we are a lot better at personal relationships, and then have the capability obviously of telling it like it is when it's necessary.
I hope I'm wrong, but I am afraid that Iraq is going to turn out to be the greatest disaster in American foreign policy - worse than Vietnam, not in the number who died, but in terms of its unintended consequences and its reverberation throughout the region.
For me, being raised in a free America made all the difference.
Iraq is a long way from the U.S., but what happens there matters a great deal here. For the risks that the leaders of a rogue state will use nuclear, chemical or biological weapons against us or our allies is the greatest security threat we face.
I saw what happened when a dictator was allowed to take over a piece of a country and the country went down the tubes. And I saw the opposite during the war when America joined the fight.
It took me quite a long time to develop a voice, and now that I have it, I am not going to be silent.
Our strategic dialogue with China can both protect American interests and uphold our principles, provided we are honest about our differences on human rights and other issues and provided we use a mix of targeted incentives and sanctions to narrow these differences.
While democracy in the long run is the most stable form of government, in the short run, it is among the most fragile.
The day-to-day making of policy is arguing all the time. You're trying to get the right approach and the right answer, and there are moments that aren't very pleasant. But in the end, you look at the overall product.
It's important that we invest in America - literally. The terrorists wanted to destroy our economy, and we can't let our system fall apart. We also have to invest in one another.
And so I think that the idea of America working with other countries to solve problems is good for us, and it is part of digging us out of the 'my way or the highway' approach that was evident in the previous eight years.
When Hillary served in the Senate, I saw her work day and night as a member of the Armed Services Committee - working with Republicans and Democrats to keep our military strong and protect our troops and their families.
