In 1920, the West ruled huge amounts of the world.

I think fundamentalism is this radical attitude toward one's own identity and civilization as compared to other people's identities and cultures.

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.

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.

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.

In the coming decades, questions of identity, meaning cultural heritage, language, and religion will play a central role in politics.

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