I believe that, one way or another, Mexico will ultimately wind up paying for the wall; even after the fact. PDJT does NOT forget.
I don’t disagree but there is no, that is, 0 evidence that Mexico pay anything.
To the contrary, Mexico is largely to fault for the present flap over illegals at the border. Mexico is not even being challenged much less brought to task for the formal Mexican support for the illegal invasion.
If Mexico was slapped violently about the head and shoulders there might not even be a need for the wall. Mexico is the National security risk
