I think the best way to control a population is to urbanize and to educate women. We have seen historically in many, many countries that once women are educated and have opportunities, and that happens when they live in cities and once they improve their economies, they no longer want to have eight kids. They want to have one or two or maybe three. And that is much more sustainable for them because they have other opportunities.

In the nearer term, the likeliest source of risk is a conflict between China and the U.S. These are now the two largest economies in the world, and the combination of their economic interdependence, the sharp differences in their political and economic values, and the growing divergence in their interests makes this relationship potentially dangerous for everyone who might be affected by it - which means pretty much everyone.

There is too large a divergence at the moment in the interests and values of the world's most powerful states.

I would rather people not smoke. I certainly appreciate the fact that smoking is not legal in restaurants and bars. That used to stop me from going out at night because you'd go someplace and your clothes would reek and you wouldn't enjoy the experience and that affects your rights. It's always a question.

Berlin is still a very edgy place, a very cosmopolitan place. It's a place where completely different ideas and cultures come together and clash in a very warm way. In a very warm-hearted way. It's a very young city. It's a vibrant city. It's an exciting city. It's a city that's also scarred by history. I think that's to be celebrated and graffiti is to be celebrated. Graffiti in Berlin is very different than when they spray something on the wall dividing the west bank and Israel. And should be treated as such in Berlin.

I believe that if you go and ask a chief executive of a Goldman Sachs or a BP, and they answer you honestly they want monopolies, they want government subsidies, they want preferences - they're not interested in free markets.
