Arnold Ahlert: "An additional 12 million illegal aliens attempting to enter the country in the hopes that still another round of amnesty will pass might be a modest total. That's because Americans tend to think of illegal immigration as a problem almost wholly associated with nations to our south. The world is a far bigger place, and an American 'welcome mat' -- comprised of self-interested constituencies coupled with widespread contempt for the law -- suggests we may be dealing with a far larger and more widespread assault on our borders in the future. And that's assuming the word 'border' retains any meaning at all in America's future."
