Was there something about ropes, ladders, and shovels that wasn't clear? Wall's can't stop someone determined to get over/under it; security doesn't come from a wall, it comes from boots on the ground. It's not a meme, it's a fact. Beyond that, putting up a wall presumes incorrectly that that's how illegals get into the country, it's not. One only has to get a tourist visa and then not leave to get into the country, no wall stops that; walls are for show and are a waste of money. Then entire border of the country is open, putting a wall on a small part of the southern border is simply idiotic.
