The Sources of American Power

A Foreign Policy for a Changed World

By Jake Sullivan

Nothing in world politics is inevitable. The underlying elements of national power, such as demography, geography, and natural resources, matter, but history shows that these are not enough to determine which countries will shape the future.

By Robert M. Gates

The United States now confronts graver threats to its security than it has in decades, perhaps ever. Never before has it faced four allied antagonists at the same time—Russia, China, North Korea, and Iran—whose collective nuclear arsenal could within a few years be nearly double the size of its own. Not since the Korean War has the United States had to contend with powerful military rivals in both Europe and Asia. And no one alive can remember a time when an adversary had as much economic, scientific, technological, and military power as China does today.
