People are now starting to explain the Cold War. Even in the crises at that time the survival of millions of people was at stake. And we (the USA) had to threaten the other super power with retaliation to prevent it from doing something to us. Today we live in a world in which a lot of things are in flux. That creates a lot of fear. But it is also a time of great opportunity. And I would call on today's statesmen to not allow their thinking to be directed by fear.

The mistake we make with many people - not just Russia - is that we believe we have the model, and there is a sort of a condescension in our dialogue with other societies, which was especially painful in several administrations to Russia. I think in Russia, the Yeltsin period is not considered a period of great achievement, but a period of corruption and humiliation.

I was always convinced that decent people in the case of Vietnam, highly intelligent, decent people, got us involved because they had made, in part, a misjudgment about the nature of the communist system and the unity of the communist world and the degree to which the experience of Europe could be repeated in Vietnam.

For my generation the relationship with Europe was the central point of American foreign policy. Even during my time in government there was disagreement, sometimes very strong disagreement. But they were all like arguments within a family. I am not sure if the generation which doesn't have these experiences has the same view of things.

You're 18 points down [in the polls]... You might as well do what's right.

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.

Now we have a whole series of problems - energy, environment, proliferation - which go beyond the nation. And we also know that a conflict between major powers would be a catastrophe for which there is no compensation in anything you can gain.
