I would do it the way it's being done now. When laws are broken, you track down those responsible, directly or indirectly. They've arrested hundreds of people in the wake of the Sept. 11th attacks. Does that mean there will still be bad guys out there you don't catch? Yes. In the same way there are those who will commit murder tomorrow, but who can't be arrested today because they've committed no crime yet.
It certainly is true that foreign nationals don't have a Constitutional right to be here. (I expect the Supremes might even disagree with that, but we talk original intent here on FR.) But the presence of foreign nationals here in the U.S. serves the purposes of the country. There, I said it. We are, on the whole, better off because we allow foreign nationals to be here. And I don't except Sept. 11th in the calculation, either; don't forget that many of the innocent people who were murdered were foreign nationals themselves.
Besides the deleterious effects to our nation, I do not believe that a large reduction in foreign nationals in the U.S. would significantly reduce the risk of terrorism. It would serve only to satisfy the xenophobic urges of some Americans. That's the sum total of the benefit to the U.S.
C'mon, Physicist. I was talking specifically about ARAB foriegn nationals. I want to deport ARAB foriegn nationals. Not all of them.
Why do you continue to fail to adress this point?
