The lack of a wall directly permits invasions of the USA, or requires identifying and massing troops on the border in response to each "Caravan".
Since the next thing our enemies will try is two, three or four "caravans" at the same time, we might as well just build the wall.
Yeah exactly, that's the stupidity and nonsense I was talking about ^^
But at least the guys are committed to build the world they want. If everyone was that way we would have a much better, though much different, world by now.
