oh, I see, so the Great Wall of China or the Ligne Maginot -- both
built with the best technology available at the time, both to keep
some folks *out*, both just as successful -- would be better
examples then?

Poor examples. Both were designed to stop a military assault.

What is happening on the southern border of the U.S. is far more insidious
than that.
