A wall is a dumb idea. If people have the incentive to come, they will come. They’ll tunnel deeper, use submarines, who knows what. What we need is to take away the incentives. If illegals have no anchor babies, no welfare, no healthcare, no drivers licenses, no tax rebates, no jobs, no etc. they won’t come. No wall needed.
The Great Wall of China was a dumb idea? The Berlin Wall and the wall around Jerusalem and the Vatican are dumb ideas too? You are so naive. Submarines under the Rio Grand? LOL
Walls work. People opposing them have dumb ideas. History proves it.
We certainly need to do that, wall or no wall.
What about all the criminal elements in the drug trade? You won’t stop drugs demand but you can stop drug cartels at the border with a wall.
Oh, please. Israel has walls (er, fences) and they work. The Hungarians have just put up fences and they are working. If you go to Europe you will see myriad walled cities from centuries ago and they worked. It’s not a total solution as you point out. Remember: our enemies want in and it’s not because they want to make a living here. That’s why we need barriers.
Why not both?
