Jack, if you have 50 miles of a little 75 year old cattle fence that is nothing but wooden posts and thin wires pulled across with big gaps in between the wires, and fallen down in many places, is that an actual border? Should it be left like that? Is that doing anything? Because that is basically all that there was for huge sections of the border. If even that much, huge sections had even less than that. That's why everyone can just walk in, all they have to do is step over a 4 foot high chainlink fence or some little wooden boards with gaps they can just walk right through.
Here are some actual pictures of the US Mexico border fences that you think are so perfect and impenetrable quality that Trump is just wasting his time with the new wall. "Why are you replacing it? It was good enough already! That doesn't count as building a wall since there was a fence there already!"
Here is the new wall next to the old one it's replacing.
So yes, every mile of wall that has been being built is all new wall. Where it has replaced worthless dilapidated cattle fences that anyone in the world can just walk right through, replaced with an actual and secure border, that is a new and secure wall being built.
Jack, if the door to your house was made of tissue paper and had many holes through it, and you removed the tissue paper and put in an actual thick wooden door with locks on it. Would you be saying "That's fake, that's not a new door, there already was a door there!" Or would you realize that it is important to have a real actual door, and that the tissue paper that anybody can effortlessly stick their hand right through it was not doing anything to help.
It's simple. You got caught in a lie, but you are too proud to ever change your mind, so you are grasping at straws trying to find some way out of admitting that you are wrong.
Wall is being built a mile every day. And the new wall has stopped 80% of all illegal immigrants in that area. And the only reason it's only 80% and not 100% is because they haven't finished building it yet so they ran around the edge. But nobody has ever really gotten across that new wall ever before if you don't count going around the unfinished edge.
