And the big question for the West, of course, and to the Europeans is, what other countries, which were formerly part of the Soviet bloc, should be incorporated into western institutions?

There has been an Irish lobby that has impacted U.S. foreign policy for a century and a half, and at times made our relations with Great Britain very difficult. Other comparable lobbies exist.

Countries will cooperate with each other, and are more likely to cooperate with each other when they share a common culture, as is most dramatically illustrated in the European Union. But other groupings of countries are emerging in East Asia and in South America. Basically, as I said, these politics will be oriented around, in large part, cultural similarities and cultural antagonism.

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.

But then I came to the conclusion that no, while there may be an immigration problem, it isn't really a serious problem. The really serious problem is assimilation.

Since the revolution of the 18th century, America has basically had an ideology of liberal democracy and constitutionalism.

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.
