After the '30s, we said, "no more Munichs." And it got us in a lot of problems. Then we said, "No more Vietnams." Now if we say, "No more Iraqs," the next one won't be an Iraq. It will be something different. You can't learn lessons.

The art of diplomacy is to take an opportunity and turn it into something.

Much of what we know about mathematics and trade comes from the Arabs. Then came stagnation, and now they're the West's whipping boy. This is a problem that cannot be solved overnight, and certainly not militarily.

The Russians are not going to do what we want them to do because we want them to do it.

America wants to work with friends, with allies, with people of good will, to make this a better world.

An idea can be as flawless as can be, but its execution will always be full of mistakes.

But, if you believe we should go around the world overturning regimes to make little United States, I don't agree with that, because I don't think we're capable of doing that.
