Back when Jimmy Carter first started talking about a Palestinian homeland, someone suggested digging a moat along the Mexican border and using the dirt from that to construct a Palestinian homeland.

I find it amazing that you would be carping about a wall on a thread about tunnels. The thread describes in detail how ancient engineers were able to go for hundreds of kilometers under ground.

The thrust of the piece undermines your demand for a wall. The wall won’t stop anything. A dedicated tunneling effort will render it worthless

Our government will build its wall in a matter of months, just as soon as they need it to keep us in.

It's what communist dictatorships do.
