The United States can certainly defeat North Vietnam, but the United States cannot defeat a guerrilla war which is being raged from a sanctuary through a pattern of penetration, intervention, evasion, which is very difficult for a technologically advanced country like the United States to combat.

With its declining population, with people moving out of the Far East, with an enormously powerful China in the east, I think the real destiny of Russia is to become closer to the West.

The Ukrainian opposition should adopt democratic unity as its main principle, and it also must have one leader.

Hard power makes sense under some circumstances. But there's not a universal solution to global problems. A major country like the United States has to have a broadly-conceived program for effective international action, influence and cooperation with others.

Let's address the issue of how America deals with the Iraqis and how we deal with the region, recognize the fact that this is a misadventure, which it is in our interest to terminate and not to repeat. That's a rather important conclusion to draw, and a very important lesson.

Moreover, as America becomes an increasingly multi-cultural society, it may find it more difficult to fashion a consensus on foreign policy issues, except in the circumstance of a truly massive and widely perceived direct external threat.

I think the US has the right to have its own national security policy. I think most Americans would agree with that. And therefore clarity on this issue is important and especially if we commit ourselves, explicitly and bindingly, to Israel's security.
