I don't know what will happen 100 years from now.

The relations between countries in the coming decade are most likely to reflect their cultural commitments, their cultural ties and antagonism with other countries.

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.

The question really is what will be the central focus of global politics in the coming decades and my argument is that cultural identities and cultural antagonisms and affiliations will play not the only role but a major role.

There has been an Irish lobby that has impacted U.S. foreign policy for a century and a half, and at times made our relations with Great Britain very difficult. Other comparable lobbies exist.

Nationalism is a central ideology for people who are trying to establish their own states in which they can play a dominant role.

A lot of people tend to think I'm a dogmatic ideologue, which I'm not.
