The Ft. Hood terrorism. A black professor punches a woman who dared disagree with his views on white privilege. Obama's pal Prof. Gates flies into a rage when cops respond to a possible burglary at his house. Pat Buchanan's take: In Arkansas last year, a Muslim opposed to the U.S. wars shot two soldiers at a recruitment center, killing one. In Kuwait, before the invasion of Iraq, a Muslim soldier threw a grenade into the tent of his commanding officer, killing two and wounding 14. This is not to suggest that all American Muslims or Arabs should be citizens under suspicion. Muslims have died fighting in Afghanistan and Iraq, as German-Americans died fighting against Germany in two world wars. But it is to say this: America is unraveling. No longer are we one nation and one people. Tens of millions have come and tens of millions are coming whose first loyalty is to the kinfolk and country they left behind, and to the faith they carry in their hearts. And if, in our long war against "Islamofascism," we are seen as trampling on their nation, faith or kinsmen, they will see us, as Hasan came to see us, as the enemy of their sacred identity. There is no American Melting Pot anymore. It was discarded by our elites as an instrument of cultural genocide. Now we celebrate America as the most multiracial, multiethnic, multicultural country on earth, the Universal Nation of Ben Wattenberg's warblings. And, yet, we are surprised by ethnic espionage in our midst, the cursing of America from mosques in our cities, the news that Somali immigrants are going home to fight our Somali allies, and that illegal aliens march under Mexican flags to demand American citizenship. Eisenhower's America was a nation of 160 million with a Euro-Christian core and a culture all its own. We were a people then. And when we have become, in 2050, a stew of 435 millions, of every creed, culture, color and country of Earth, what holds us together then?
