Meh... Honestly, I was never impressed with Trump's wall to begin with. It's just not practical for what it tries to achieve. The problem with walls is that people will always try and pick at them to get through. You can't just put up a fence and expect no one to cross it - especially when you use materials that are easily breached with power tools you get from any hardware store.
Take a look at history. This isn't the first time people put up massive walls that cover huge lengths of distance to keep people out. When you look at famous walls like Hadrian's Wall or the Great Wall of China, they aren't very impressive fortifications by themselves, but they use the terrain to give a better defensive position, and most importantly, they were
manned.
Instead of just throwing exorbitant amounts of money to build a monumental ego stroke made of paper and sticks, we could spend half of that on a squatter structure and use the rest of that money to have it manned. You could even have intermitent stations of reserve troops that we could send to specific areas in case large groups of people tried to breach specific sections of wall. Hell, we certainly have enough military on hand to do that, at least.
Whether anyone agrees with the wall or not, the whole thing was handled poorly from it's inception, imo. It was a waste of money.
