Mexico's entire country relies on the US border being a pressure release valve. When sociopolitical pressures that would push them to vote the Marxists out of power get too bad, they just encourage people to leave to the US instead.
There is exactly 0.000000000000% chance that the Marxists in Mexico ever punish border crossers or wetback caravans for us. This is before we consider the Cartels having de-facto taken over large portions of their country (and not small amounts of ours).
If we want to punish illegals, we have to do it ourselves, and the current demoralization is such that the idea of literally locking up illegals instead of just releasing them out of the country like a naughty naughty mouse caught in the kitchen is literally unthinkable.
America could start putting illegals in federal pound them up the ass prison when caught instead of just deporting them. Imagine if the calculus isn't "they might catch me and I'll have to sneak back in, darnit" but "they might catch me and put me in jail for 10 years."
Am I crazy? Why hasn't this been an option? It feels like it's one of those moments when an option has been artificially removed from the table and I can't tell why.
