Leadership must be established from the top down.

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

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.

The war between the Iranians and Iraqis is a touchy issue. To be quite honest, they each other's guts. It was not responsible to let one of our ships be put into a war zone like that.

Seventeen years after the Cold War, how can it be in the Unites States' national security interest for the President of Russia to have only a few minutes to decide whether to fire his nuclear weapons or lose them in response to what could be a false warning?

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.

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.
