What about tunnels? Israel has a wall, but there are tunnels.
We need land mines and troops. And mostly, a government that says, “If you come here illegally, you will be stripped of assets and deported with a criminal record. You will never be allowed here again. Any employer that hires you will be fined/penalized.”

Where are there tunnels under the wall?
Where is there a wall along a river border?
