The windfall of great riches can, if mismanaged, make things worse, not better, for the recipients.

Let me remind you all that the first task of American foreign policy is to reduce threats to the United States.

The windfall of great riches can, if mismanaged, make things worse, not better, for the recipients.

To call the American role in the world imperial was, for many who did so, a way of asserting that the United States was misusing its power beyond its borders and, in so doing, subverting its founding political principles within them.

The less oil the world uses, the less important the region that has so much of it becomes.

While analogies are useful, however, they can also be misleading. They smuggle in assumptions that can be wrong.

American power confers benefits on most inhabitants of the planet, even on many who dislike it and some who actively oppose it, because the United States plays a major, constructive, and historically unprecedented role in the world.
