Maybe Iraq will come back and become the dominant power among Arab countries. That seems to me as conceivable.

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

I wouldn't rule out the possibility of Muslim or at least Arab countries developing some form of organization comparable to the European Union. I don't think that's very likely, but it conceivably could happen.

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

Hispanics speak Spanish or Portuguese, which are languages we Americans are familiar with, so it doesn't seem to pose the same types of problems as Arabic-speaking Muslims do in Europe.

Countries will cooperate with each other, and are more likely to cooperate with each other when they share a common culture, as is most dramatically illustrated in the European Union. But other groupings of countries are emerging in East Asia and in South America. Basically, as I said, these politics will be oriented around, in large part, cultural similarities and cultural antagonism.

Quite obviously power will continue to play a central role in global politics as it always does. But usually there is something else.
