America's long and silent wall

Walls are contentious as of late. They have been in use historically. One, Hadrian’s Wall, defined a geographical limit to the Roman Empire. The Berlin Wall and the snipers posted on it kept East Germans from a taste of freedom. There are other walls in place or planned to keep unwanted immigrants from moving to places like Hungary, Slovenia, and elsewhere in the EU.

There are calls for a wall to keep people from crossing into the United States illegally. Demands for walls and barbed wire are growing worldwide. Sad, but nothing new.
