Samuel P. Huntington — American Sociologist born on April 18, 1927, died on December 24, 2008

Samuel Phillips Huntington was an influential American conservative political scientist, adviser and academic. He spent more than half a century at Harvard University, where he was director of Harvard's Center for International Affairs and the Albert J. Weatherhead III University Professor. During the Carter administration, Huntington was the White House Coordinator of Security Planning for the National Security Council. He is most well known by his 1993 theory, "The Clash of Civilizations", of a post-Cold War new world order. He argued that future wars would be fought not between countries, but between cultures, and that Islamic extremism would become the biggest threat to Western world domination. Huntington is credited with helping to shape U.S. views on civilian-military relations, political development, and comparative government... (wikipedia)

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.
It was this society and culture that among other things - including economic opportunities here and repression in Europe - attracted subsequent generations of immigrants to this country.
Thus, biologically speaking the American people are literally only half an immigrant people.
The British were white, English, and Protestant, just as we were. They had to have some other basis on which to justify independence, and happily they were able to formulate the inalienable truths set forth in the Declaration.
The great problem there is we have to have the cooperation of those other Asian countries.
