We fought a military war; our opponents fought a political one. We sought physical attrition; our opponents aimed for our psychological exhaustion. In the process we lost sight of one of the cardinal maxims of guerrilla war: the guerrilla wins if he does not lose. The conventional army loses if it does not win. The North Vietnamese used their armed forces the way a bull-fighter uses his cape to keep us lunging in areas of marginal political importance.

When I first saw China, there were no automobiles. There were no supermarkets. There were no high-rise buildings. There were no consumer goods. There were no restaurants that were at least accessible that foreigners could see. It was a Stalinist society, and a very poor Stalinist society. So the economic system has totally changed, and the private sector in the economic system is now the dominant sector. It didn't exist at all as late as 1979.

The greatest need of the contemporary international system is an agreed concept of order.

Don't be too ambitious. Do the most important thing you can think of doing every year and then your career will take care of itself.

In the short term, it would not have made it possible to resume relations, because in the Chinese mind, the humiliation of China started with the annexation of Taiwan by Japan. If the United States had suddenly declared Taiwan as a separate state - for which we would have had no support among other nations - the consequences would have been giving up our relationship with China and committing ourselves to a long-term conflict with China.

I don't consider China a communist state, no. I know that sounds paradoxical, but it's my view.

Now when I bore people at a party they think it's their fault.
