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.

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.

The major difference for us in America with respect to Hispanic immigration is that it is so large and that it is coming from neighboring countries rather than those countries off the Atlantic or Pacific. That creates different issues and different problems for us as compared to the past. It is still very different, however, from the situation in Europe where we see people with a very different non-European religion coming from neighboring 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.

Every civilization sees itself as the center of the world and writes its history as the central drama of human history.

Some Westerners […] have argued that the West does not have problems with Islam but only with violent Islamist extremists. Fourteen hundred years of history demonstrate otherwise.

Thus, biologically speaking the American people are literally only half an immigrant people.
