One of the things I learned as president is that your life is just not going to unfold the way you want it to. There will be surprises, challenges, and therefore the question is how you deal with the unexpected.
Let me start off by saying that in 2000 I said, 'Vote for me. I'm an agent of change.' In 2004, I said, 'I'm not interested in change - I want to continue as president.' Every candidate has got to say 'change.' That's what the American people expect.
I do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States
I've come to embrace the notion that I haven't done enough in my life. I've come to confirm that one's title, even a title like president of the United States, says very little about how well one's life has been led. No matter how much you've done or how successful you've been, there's always more to do, always more to learn, and always more to achieve.
Both President Kennedy and President Reagan were roundly criticized by parts of the foreign policy establishment that felt they were being weak by engaging our adversaries. So some of it is built into a political lexicon that makes you sound tougher if you don't talk to somebody, and rather, very loudly, wield a big stick.
I love Obama. He's my favorite president of all time. I have a giant picture in my apartment in New York that is of his Chicago Tribune cover, Mr. President.
The president and the executive branch are always going to have greater latitude and greater authority when it comes to protecting America because sometimes you just have to respond quickly and not everything that is a danger can be publicized and be subject to open debate, but there have to be some guardrails.
