Did you know, Don, that the ancient Egyptians wanted to build a wall to keep pastoralist nomads out of the Nile Delta? Yeah, it didn’t work.
Neferti, (1900 B.C.)-
All happiness has gone away, the land is cast down in trouble because of those feeders, Asiatics (sttyw) who are throughout the land. Enemies have arisen in the East, Asiatics (‘amu) have come down to Egypt … One will build the “Walls of the Ruler” to prevent Asiatics (‘amu) from going down to Egypt. They beg for water in the customary manner in order to let their flocks drink.
Old ideas that never worked: the Trump Way.
