From a geo-strategic point of view, I consider Iran a bigger problem than the Islamic State. ISIS is a group of adventurers with a very aggressive ideology. But they have to conquer more and more territory before they can became a geo-strategic, permanent reality. I think a conflict with ISIS - important as it is - is more manageable than a confrontation with Iran.

I don't think that that's a desirable option for us. Besides, it wouldn't work, because there are too many other countries that are willing to work economically with China. But I don't think the basic relationship depends on economics. It depends on a political understanding of what is required for peace in Asia.

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.

The Western concept of democracy is based on the idea that the loser of an election has the possibility next time round of being the winner. But in the case of an ethnically or religiously divided country, in which minorities don't live peacefully together, this necessary balance can't be properly guaranteed by democracy. When each ethnic group arms itself, it is not surprising that the army of a new state is viewed by part of the population as an ideological militia.

It is frankly a mistake of amateurs to believe you can gain the upper hand in a diplomatic negotiation.

I do not believe that Putin intends to leave office in a Cold War atmosphere with the United States.

To have striven so hard, to have molded a public personality out of so amorphous an identity, to have sustained that superhuman effort only to end with every weakness disclosed and every error compounding the downfall--that was a fate of biblical proportions. Evidently the Deity would not tolerate the presumption that all can be manipulated; an object lesson of the limits of human presumption was necessary.
