We have an orientation that tends to make us think that everything is our responsibility and that we should be doing this. It is the Iraqis' country, 28 million of them. They are perfectly capable of running that country.

Be precise. A lack of precision is dangerous when the margin of error is small.

Death has a tendency to encourage a depressing view of war.

There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns - the ones we don't know we don't know.

An institution that...would permit Iraq, a terrorist state that refuses to disarm, to become soon the chair of the United Nations Commission on Disarmament, and which recently elected Libya - a terrorist state - to chair the United Nations Commission on Human Rights of all things, seems not to be even struggling to regain credibility. That these acts of irresponsibility could happen now, at this moment in history, is breathtaking.

Success tends to go not to the person who is error-free, because he also tends to be risk-averse. Rather it goes to the person who recognizes that life is pretty much a percentage business. It isn't making mistakes that's critical; it's correcting them and getting on with the principal task.

The way to do well is to do well.
