I am all for making the borders more secure.
This is what I would like to see done: First, close down all foreign military bases across the world and bring every soldier home. We then line, both north and south, a series of military bases which we will place the military to make sure the borders are secure. Second, create a set of laws that will hold employers and landlords criminally liable for hiring and renting to illegal aliens. Also have those who are in this country, regardless of age, illegal criminal responsible which they can face prison time prior to deportation. Third, go over our immigration policies and make them fairer for all those who seek to enter this country legally. Make country of origin be considered moot. It wouldn't matter if the person comes from Mexico or Canada, Sweden or Japan, they would be treated the same. No playing favorites.
