Also, of course, for most of this time most Americans thought of America as a white country with, at best, only a very segregated and subordinate role for blacks.

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.

I think in theory, the United States finds it much easier to deal with situations where there is a leading country. You can go to the leaders of that country and say, for example, to India, "There are all these problems in Bangladesh, we really have to do something about it, what do you suggest we can do to work out a common policy?" But when you don't have the equivalent of India, you have to go capital to capital trying to put together a coalition, which is extraordinarily difficult, especially in the Arab world, because of the historic rivalries and branches of Islam.

Critics say that America is a lie because its reality falls so far short of its ideals. They are wrong. America is not a lie; it is a disappointment. But it can be a disappointment only because it is also a hope.

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

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.

Except under rare circumstances, I don't write responses to criticism.
