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.

Leadership must be established from the top down.

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.

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.

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.

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.
