The Oval Office is a place where there's been, obviously, a lot of amazing experiences over a seven-and-a-half year period. My presidency is one where I've had to make some very tough decisions. I guess some presidencies are kind of - were real smooth, there were no real big issues. Well, that's not the way mine is.

Imagine a world in which you had Saddam Hussein, who had the capacity to make a weapon of mass destruction, who was paying suiciders to kill innocent life. Imagine what the world would be like with him in power. The idea is to try to help change the Middle East. Part of the reason we went into Iraq was we thought he had weapons of mass destruction. It turns out he didn't, but he had the capacity to make weapons of mass destruction.

Americans should not expect one battle, but a lengthy campaign, unlike any other we have ever seen. It may include dramatic strikes, visible on TV, and covert operations, secret even in success.

We must all hear the universal call to like your neighbor just like you like to be liked yourself.

This way of life is worth defending.

I believe strongly that to whom much is given, much is required - we are a blessed nation - and that the United States could affect suffering in a positive way.

I've changed my style somewhat, as you know. I'm less - I pontificate less, although it may be hard to tell it from this show. And I'm more interacting with people.
