The basis of association and antagonism among countries has changed over time.

The United States has been an immigrant country. The Hispanics who come here are largely from Mexico and South America. They are Catholics, but that is an American religion. One-third of our population is Catholic so that does not have the same impact as Muslims coming into Europe.

Also, of course, for most of this time most Americans thought of America as a white country with, at best, only a very segregated and subordinate role for blacks.

When I think of countries that I enjoyed visiting, that I would want to go back to, Italy would be one, Japan would be another. I've only been to Indonesia once or twice and it seems like such a fascinating country. I guess India certainly.

Obviously Muslim societies, like societies elsewhere, are becoming increasingly urban, many are becoming industrial, but since so many have oil and gas, they don't have a great impetus. But again, the revenue that natural resources produce gives them the capability and so countries like Iran are beginning to develop an industrial component.

Well, I think the United States first of all has to recognize the world for what it is.

There are lots of conflicts going on in the Middle East. It is unclear as to which country will emerge, if any, as the dominant or hegemonic power in the Middle East.
