What the U.S.-Mexico border wall would look like in Europe
January 29, 2018 by ORION JONES
The length of the U.S.-Mexico border is not actually agreed upon. The International Boundary and Water Commission extends the border to measure 1,954 land miles, and 1,984 total miles to include water boundaries along the Rio Grande.
There is reportedly a total of 700 miles of border wall already dividing the United States and Mexico, leaving 1,200 miles of construction remaining, nearly double what currently exists.
Many of history's most famous walls have not been end-to-end constructions. The Great Wall of China, constructed to buttress the border between Mongolia and China (the world's fourth largest), was built in key strategic points only.
But modern building materials and the abolition of slavery makes any such comparison specious. (A Chinese maxim goes: Why does the Great Wall reach so high? Because it is built on the bones of slaves who died raising it.)
