With proper tactics, nuclear war need not be as destructive as it appears.

What we in America call terrorists are really groups of people that reject the international system

Each success only buys an admission ticket to a more difficult problem.

The history of things that didn't happen has never been written.

The members of the Islamic Staye have cut the throat of an American on television. This is an insult to the United States, which requires that we demonstrate that this is not an act that is free. I would strongly favor a strong attack on ISIS for a period that is related to the murder of the American.

I have been observing China for more than 30 years and am impressed how logically and wisely it tackles its problems. Obviously the international system could be unbalanced by China's rising power - if we don't prepare ourselves for the new competitive situation, that is. But it is an economic challenge, not aggression on the level of Hitler.

I see the future of China as growth. I think that historically China has often gone through periods of consolidation, and then periods of sort of weakening central authority. They undoubtedly face tremendous challenges.
