Jimmy Carter: Right (page 2)

Post-Presidency, Nobel lecture (2002)
Context: The world has changed greatly since I left the White House. Now there is only one superpower, with unprecedented military and economic strength. The coming budget for American armaments will be greater than those of the next fifteen nations combined, and there are troops from the United States in many countries throughout the world. Our gross national economy exceeds that of the three countries that follow us, and our nation's voice most often prevails as decisions are made concerning trade, humanitarian assistance, and the allocation of global wealth. This dominant status is unlikely to change in our lifetimes.
Great American power and responsibility are not unprecedented, and have been used with restraint and great benefit in the past. We have not assumed that super strength guarantees super wisdom, and we have consistently reached out to the international community to ensure that our own power and influence are tempered by the best common judgment.
Within our country, ultimate decisions are made through democratic means, which tend to moderate radical or ill-advised proposals. Constrained and inspired by historic constitutional principles, our nation has endeavored for more than two hundred years to follow the now almost universal ideals of freedom, human rights, and justice for all.
