If the six-nation forums dealing with Iran and North Korea suffer comparable failures, the consequence will be a world of unchecked proliferation, not controlled by either governing principles or functioning institutions. A modern, strong, peaceful Iran could become a pillar of stability and progress in the region. This cannot happen unless Iran's leaders decide whether they are representing a cause or a nation - whether their basic motivation is crusading or international cooperation. The goal of the diplomacy of the Six should be to oblige Iran to confront this choice.

I know Hillary Clinton as a person. And as a personal friend, I would say yes, she'd be a good president. But she'd put me under a great conflict of interest if she were a candidate because I intend to support the Republicans.

My country's history, Mr. President, tells us that it is possible to fashion unity while cherishing diversity, that common action is possible despite the variety of races, interests, and beliefs we see here in this chamber. Progress and peace and justice are attainable. So we say to all peoples and governments: Let us fashion together a new world order.

I don't stand on protocol. Just call me your Excellency.

Most high officials leave office with the perceptions and insights with which they entered.

The attitude of the West and of Russia towards a crisis like Ukraine is diametrically different. The West is trying to establish the legality of any established border. For Russia, Ukraine is part of the Russian patrimony. A Russian state was created around Kiev about 1,200 years ago. Ukraine itself has been part of Russia for 500 years, and I would say most Russians consider it part of Russian patrimony. The ideal solution would be to have a Ukraine like Finland or Austria that can be a bridge between these two rather than an outpost.

The US must carry out some act somewhere in the world which shows its determination to continue to be a world power.
