If a new president personalizes a rather different concept of America and a different sense of America's mission in the world than has been the case with president George W. Bush, then that almost automatically will help to improve America's global image. But the tangibles involving the war and the economy are not going to be easy to fix.

The Israelis are becoming increasingly like the white supremacist South Africans, viewing the Palestinians as a lower form of life, not hesitating to kill a great many of them and justifying this on the grounds that they are being the objects of terrorism, which is true.

Iraq may have been a preview of that, but it's still redeemable if we get out fast. In a war with Iran, we'll get dragged down for 20 or 30 years. The world will condemn us. We will lose our position in the world.

I'm perfectly willing to say no more Iraqs, which means no more unilateral starting of the war on false claims, false information, and a complete misunderstanding of the nature of the situation in the region.

America is the only superpower. But our leadership is being tested in the Middle East, and some of the things that we have done in the Middle East are contributing to a potential explosion region-wide. And if that explosion gets out of hand, we may end up being bogged down for many years to come in a conflict that will be profoundly damaging to our capacity to exercise our power, to address the problems implicit in this global awakening, and we may face a world in which much of the world turns away from us, seeks its own equilibrium, but probably slides into a growing chaos.

It certainly would be possible for America to redefine its role in the world, especially if, in the short run, America is able to cope effectively with the ongoing dilemma in the Middle East.

No matter how deeply disturbing the thought of using the environment to manipulate behavior for national advantages to some, the technology permitting such use will very probably develop within the next few decades.
