We are in a race between cooperation and catastrophe, and the threat is outrunning our response.

It's very hard for Europe, the US and Russia to have much influence on the growing problems elsewhere in the world unless we have our own backyard in a more stable and cooperative atmosphere.

I don't think that within a certain amount of time we can get rid of all nuclear weapons. But I do believe that, step by step, we could get others to join us. I call it going up the mountain. We can get to the top eventually, but we have to get to base camp first. Right now, we are in the valley. So we have a long way to go, but maybe our children or our grandchildren will see the top of the mountain.

There is a pervasive mistrust that grew out of the Cold War and still continues today - even though there are a lot more mutual interests between Europe, Russia and the United States than ever before. But the way we organize things today, it takes years to negotiate. By the time you get a result, the technology has far outrun the policy. So we have to start a dynamic, sustainable type of policy deliberations that can catch up with technology.

I don't know how you make a record on liberal and conservative these days. We've had a conservative Republican Congress, so to speak, and a conservative president, and we've run up one of the most astounding deficits in the history of our nation.

You have to pay the price. You will find that everything in life exacts a price, and you will have to decide whether the price is worth the prize.

Some people think we will see a nuclear explosion in Europe or the United States within the next 10 years. Will it happen? Sure, it's possible. But I think we can greatly diminish that risk. The only way you can do that is through cooperation, and it has to be global.
