All aspects are realistic and practical. There is only one real obstacle. George Bush. He *wants* the Mexican influx.
What motivates him and his reasoning processes is unknown to me, and in some ways I don’t care. But I don’t believe it is “compassion”. And in a way it doesn’t matter.
As you have outlined, we know how to keep them out. What we don’t know is how to get Bush and our government to actually do it.
We should all care. I believe his motivation is the New World Order, with the US being part of the North American Union. Open borders, new money and new leadership under the U.N.
