People have multiple identities.

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

It is my hypothesis that the fundamental source of conflict in this new [post-Cold-War] world will not be primarily ideological or primarily economic. The great divisions among humankind and the dominating source of conflict will be cultural. Nation states will remain the most powerful actors in world affairs, but the principal conflicts of global politics will occur between nations and groups of different civilizations. The clash of civilizations will dominate global politics. The fault lines between civilizations will be the battle lines of the future.

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.

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.

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.

Fascism and communism have not entirely disappeared but have been sidelined certainly, and liberal democracy has come to be accepted, in theory at least, around the world, if not always in practice.
