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.

Everything today is "transient." Technology and its ability to empower actors large and small evolve so quickly that we have to get used to living in a world that exists in a more or less constant state of flux.

Whether it is gun control lobby, health care lobby, or abortion, pro-choice lobby, whatever it is, people are always trying to say that it is about restricting rights and they are never really prepared to talk about what the honest tradeoffs are. One of the things we need to do a better job of is actually painting those tradeoffs.

The real question is not are there other forms of life in the universe, but are there other intelligent forms of life out there right now. Because the universe is not only really big but it's also really long. It's been around for a long time; it's going to be around for a long time.

NASA is increasingly not the future of space exploration. I love the fact that we have private sector folks devoting a lot of money to stimulate innovation in space technology.

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.
