I would say the special experience of American wartime policy in the last 40 years, from Vietnam on, is that the war itself became controversial in the country and that the most important thing we need in the current situation is, whatever disagreements there may be on tactics, that the legitimacy of the war itself does not become a subject of controversy. We have to start with the assumption, obviously, that whatever administration is conducting a war wants to end it.

Every time there has been an attempt to disturb it, it led to two things. It led to immediate intense conflict with China, and it led to a reaffirmation in the end, because nobody wanted a major confrontation with China to this principle of a "one China" policy within which Taiwan is finding a place now. Its own position has greatly improved since the Nixon policy. It is richer, it is stronger and it is participating in many international organizations.

What is applicable is to understand that first of all China has undergone a huge revolution in the last years. Anyone who saw China as I did in 1971 - and for that matter even in 1979, because not much had changed between 1971 and 1979 - and sees China today, knows one is in a different economic system.

In Asia, the nation state still is extremely vital, and of course, then in Africa, a whole new pattern is emerging because the states in Africa reflected the preferences of the colonial powers when they were established.

I've often said that the desire to lecture China on how it should behave in the world is wrong. China was around for thousands of years even before America existed. It could even be that China's growing power will allow itself to be slowed down. But as long as this immense empire doesn't fall apart, it will become an important factor in global politics.

They [American forces] are there as an expression of the American national interest to prevent the Iranian combination of imperialism and fundamentalist ideology from dominating a region on which the energy supplies of the industrial democracies depend.

University politics make me long for the simplicity of the Middle East.
