We would probably end up annexing Mexico, well, their southern border might be a bit easier to patrol.lol
In that case whatever we annexed would become a prosperous area. If they, however, were to take over part of their so called Aztlan, it would no doubt eventually become a dump like most of Mexico today.
No way, wipe them out and seal the border with the military with orders to shoot on sight.
At the rate we're going, Mexico will annex us.
We thought about annexing Mexico in the 1800's when the place still had some potential. At this point, I think Mexico would be more of a liability than an asset. We need to do many things to bring about greater border security, but we should not rule out the use of military force.
