When you have increased migration of peoples and ethnic and religious minorities, you develop a set of rules and language the larger society can accept and the minority community can accept.

And the big question for the West, of course, and to the Europeans is, what other countries, which were formerly part of the Soviet bloc, should be incorporated into western institutions?

The larger society has to recognize some degree of autonomy for the minority: the right to practice their own religion and way of life and to some extent their language.

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.

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

Obviously there are divisions within the West and divisions within Islam - there are different sects, different communities, different countries. So neither one is homogenous at all. But they do have things in common.

There will be associations and partnerships between some Muslim countries and some Christian countries. Those already exist. And they may shift as different regimes come and go and interests change.
