State of Emergency: The Third World Invasion and Conquest of America (Hardcover)

From Booklist
In his wide-ranging argument about immigration, perennial wake-up-caller Buchanan finally seems a little despondent. The West is nearing death by drowning under a torrent of non-Westerners, the preponderance of whom, he insists, are just trying to earn more and live better than they did in their countries of origin. Some few are bad actors, but they would be manageable if the total number of immigrants were much smaller. Crucially exacerbating the crisis are attitudes fostered by original homelands and others neglected by host nations. For example, Mexico, with its permanent, inalienable citizenship and historic grudge against the U.S. for the latter's Mexican War-facilitated purchase of half of Mexico's original territory, actively discourages Mexicans in the U.S. from becoming U.S.-identified. Simultaneously, U.S. elites downplay "Americanization" in favor of transforming most of the populace into a low-wage workforce fragmented by linguistic and cultural differences. Look to Europe, which from Britain to Russia, Buchanan argues, is much nearer cultural collapse, to see the U.S. in 2050--or sooner. Ray Olson

People are always blaming the Left and calling us "cut and run" and all the rest. But your being blindsided by these people. These "Nativist" are the isolationist of the pre WWII era. They are the real threat to defeating the current enemy and are the first that once elected will not only cut and run, but they are planning to build a wall and a mine field behind them as the last one of them runs in behind our boarder with the flag in hand.

And they have no one party, they are not the same race, nor color, they don't share a religion, or a one blatant ideology, but they all have one thing in common.
We are here now, and we want to close the door on the world. We don't want your problems, we don't want your people, and we surly don't want you to bring your values and issues here. Stay out there, and we will promise to leave you alone.

These people are the biggest threat to the US that have come along in half a century. In my opinion.
