Berlin is 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.

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.

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.

We live in a fantastically wealthy country. We don't have to worry about food. We don't have to worry about clothing. We don't have to worry about our safety. It's very easy for me to be an environmentalist. It's very easy for me to care about making sure that we protect the forests and the whales, and all that stuff.

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.

I think it's fantastically narcissistic to believe that in the entire universe, with all of the planetary systems that we've already discovered and the countless others that are out there, that we are the only forms of life.

We don't gaze into a crystal ball. I do not believe that we predict things. I think political science is bad at prediction. I think what we really do well is in a number of instances where politics matters, we can do a better job of tell you what is happening now, than other people. So, we can look at Syria today. We can look at the Eurozone today. And we can look at areas where politics is a driver and we can give you a pretty good sense in those areas of here is how to understand today.
