The steady progress made by North Korea on its nuclear and missile programs is deeply concerning. The US cannot solve this problem alone. However, in order to take steps that could fundamentally affect the North Korean leadership and its decision-making, we need to work even more closely with our allies in the region who feel this threat acutely. I would urge China, in particular, to intensify its leadership role in helping to solve this crisis.

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.

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?

Leadership must be established from the top down.

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.

If you think you're a leader, and you look over your shoulder and there ain't nobody following you, man, you're just takin' a walk.

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.
