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

I've been to Egypt, Lebanon, Saudi Arabia, and Kuwait for brief visits at conferences, and they are very interesting countries.

Obviously Muslim societies, like societies elsewhere, are becoming increasingly urban, many are becoming industrial, but since so many have oil and gas, they don't have a great impetus. But again, the revenue that natural resources produce gives them the capability and so countries like Iran are beginning to develop an industrial component.

Iran of course is Shiite, while the bulk of the Arabs are Sunni, that is a problem or could be a problem. Also, there is the simple fact that Iran is non-Arab and most of the Muslims in the Middle East are Arab.

I don't say that the West is united, I don't suggest that.

I think we can expect leaders of Muslim societies to cooperate with each other on many issues just as Western societies cooperate with each other.

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.
