Frank, Tear Down Your Wall -- Trump, February 19, 2016

From CNN: the walls are there, but people are free to walk in and out of the Vatican grounds. The doors are always open.

I'm sure the wall that the Donald is proposing will also have doors that are always open. Revolving doors. Trump will put Disney in charge of a) line management; and, b) tickets. I envision a "3-day hopper" in which folks can save money by purchasing a ticket that allows them to hop back and forth between the two countries (the US and Mexico) for three days. Latinos will call the "3-day hopper" the "tres-dias-conejo" -- the Spanish word for rabbit is conejo. Not to be confused with mules which move drugs across borders.

Wow, when The Donald gets going, one never knows where things will lead. Now we see that a pre-historical builder of walls -- no doubt, a conservative -- was building walls in the Holy Land, or at least very near the Holy Land. Whatever. But no sooner do Pope Francis and Donald Trump get into argument about walls and Yahoo posts a story on that wall:

A new map of an ancient wall that extended 93 miles (150 kilometers) in Jordan has left archaeologists with a series of mysteries, including questions over when the wall was built, who built it and what its purpose was.

Known today as the "Khatt Shebib," the wall's existence was first reported in 1948, by Sir Alec Kirkbride, a British diplomat in Jordan. While traveling by airplane in Jordan, he saw a "stone wall running, for no obvious purpose, across country."

Archaeologists with the Aerial Archaeology in Jordan (AAJ) project have been investigating the remains of the wall using aerial photography. The researchers found that the wall runs north-northeast to south-southwest over a distance of 66 miles (106 km). The structure, they found, contains sections where two walls run side by side and other sections where the wall branches off.
