You have no idea how wrong you are about how I think about this.World pressure brought down the wall, and so it would also bring down a fence. As I stated, send them all back to their countries immediately as soon as they cross our border, not a bus ride to our cities, a plane ride back to their country. In short order they would quit coming if they knew they were going back. Do you really expect or think any of our future politicians would let a wall or fence stand? Once you draw a line you better be prepared to defend it forever, I don’t see that happening currently or in the near future.
The Berlin Wall kept people IN. Our Wall would keep illegals OUT.
World pressure had nothing to do with bringing down the Berlin Wall. The East was economically bankrupt. Fiscal reality brought down the wall.
If by some miracle we had a continous 50ft Wall along our entire Southern border I can't imagine some future President attempting to "bring it down." The people wont allow that -- the optics and evil intention would be obvious.
Of course, we have 60-80 illegal third worlders here so politically the Wall will likely not be built.
Without the wall, another Obama down the road would easily "invite" another 200M third world socialist scum into our dead Republic.
I fear the left will truly succeed (very soon) in fatally destroying our Republic.
