Border Issue

It's impossible to build a fence or wall along the US -Mexican border. It's thousands of miles long with impassable terrain in many places. Usually Mexico is to the south and the US to the north but sometimes Mexico is to the west and sometimes to the north of US! There are dry washes, rivers, mountains endless miles of desert terrain.

It's impossible and it'll never work. Anyone selling you on that idea is selling you blue sky.

The answer lies in more technology and more bodies to police the border. We don't need a Berlin Wall in the US. That wall came down and eventually any wall put up on the US -Mexico border will ultimately come down as well, despite the dollars we through at it.
