Certainly here in the U.S., we've had fundamentalist movements that have taken very critical and hostile attitudes toward immigration and the assimilation of immigrants into our society and culture. So these tendencies are fairly universal. The problem is what if they get out of hand and become the dominant factor in a society, which can only lead to the oppression of minorities or even to war with neighboring societies with differing cultures. That's why it seems to me it's important to try to keep these tendencies toward extremism under control.

Every civilization sees itself as the center of the world and writes its history as the central drama of human history.

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.

Turkey has its own interests and historically, Turkey conquered most of the Arab world, and the Arabs had to fight wars of liberation to free themselves from the Turks. That's in the past and that doesn't necessarily shape what is going on but it's there and it's there in people's memories.

Except under rare circumstances, I don't write responses to criticism.

As far as ideology or political beliefs are concerned, countries are very different.

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.
