(Mexico-United States border)
In the summer of 2015, presidential hopeful Donald Trump made a speech about immigration and border control. He exclaimed to the surprise of many, “I will build a great, great wall on our southern border, and I will have Mexico pay for that wall. Mark my words.” He didn’t release any specifics on his wall and no architect (to our knowledge) has been commissioned. The wall would be 1,954 miles long or about twenty times the length of the Berlin Wall but only 1/7th the size of the Great Wall of China. So, what would a Mexico-funded, U.S. owned, Trump Wall be?
