In the 19th century it was basically nationality and people trying to define their nationalism and create states which would reflect their nationalism. In the 20th century, ideology came to the fore, largely, but not exclusively, as a result of the Russian Revolution and we have fascism, communism and liberal democracy competing with each other. Well that's pretty much over.

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.

Obviously Pakistan and the U.S. are very different countries, but we have common geopolitical interests in preventing communist take over in Afghanistan and hence, now that Pakistan has a government that we can cooperate with, even though it is a military government, we are working together with them in order to promote our common interests. But obviously we also differ with Pakistan on a number of issues.

Many more people in the world are concerned about sports than human rights.

When I think of countries that I enjoyed visiting, that I would want to go back to, Italy would be one, Japan would be another. I've only been to Indonesia once or twice and it seems like such a fascinating country. I guess India certainly.

When you mention the word ideology, everyone has communism in the back of their minds, which was an entirely well formulated ideology and statement of belief. You read the Communist Manifesto and you know what the core of it is.

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.
