.Think about it. Mexico’s south border is a fraction of the size of the US / Mex border . It’s be easy and cheap to do . Most of the illegal rush is coming from central and South America anyway .
Mexico is doing much better than rest . They’d love the help with a south wall. Then we just have to worry about Mexicans sneaking in . Which would be easy to deal with as their economy thrives.
We have been giving Mexico $$$ to do just that for years and years.
