Just a word about the wall idea. It would be extremely costly, might stop the flow of illegal immigrants, but cannot offer our nation security. Our two most vulnerable points for a nuclear or biological attack by terrorists are adjacent to Tijuana and Juarez, Mexico. San Diego, California and El Paso, Texas or not only prime targets for terrorists to strike our civilian population, but the major military installation nearby.
We need to start thinking way beyond a wall, or a massive military presence along the border. The solution must secure our nation, end the mass migration, and be lasting.
What are you talking about? What's so expensive about a silly wall. Don't listen to the spin. In some places it can be bob wire. Other places chain link. Other tall corrugated metal like the Israelis are using. Don't kid yourself, we can build a wall, and if we wanted to we could pay illegals $6.25/hour to do it for us, which I happen to think is a good idea.
The main thing is to back it up with force. Not the threat of, but actual force, then the faucet will close. THEN the threat will start to be effective, but not until the peasants are shown who is boss.
