Page 4 Wall Immigration Trump The JB
I understand what you are saying but I look at this from a military perspective. When I was in the infantry we'd lay out concertina wire. We knew it wouldn't stop the enemy as they approach, but it was an obstacle to slow them down and give us time to react. That is what this wall would be. And I am not calling these would-be immigrants the enemy, just using this as an example. It would be huge, but it would be a deterrent to some, and a hindrance to others. Furthermore, once the wall is in place there are acoustic listening devices that I'm sure they'd use to listen for people digging underneath. Weak spots could be identified and patrolled. It's by no means perfect, not even close. But it is better than nothing at all.
