President Trump has a warning:

Another big Caravan heading our way. Very hard to stop without a Wall! — Donald J. Trump (@realDonaldTrump) January 18, 2019

It’s a funny thing. Trump keeps going on about his hobbyhorse wall, but as we all know, last year’s caravan from the Honduras marched straight up through Mexico along the longest route possible in order to end up in the very area with the biggest, most secure wall we have: San Diego. What’s more, as the map below shows, that’s exactly where the Army figured they’d go. And the alternate routes were all big cities with walls too: El Paso, Piedras Negras, Laredo, McAllen, and Brownsville:

These migrant caravans are positively enthralled by the wall we already have! And they’re really easy to stop: When they get to Tijuana—or whatever legal port of entry they’re heading for—you just refuse to let them in so they can apply for asylum. Piece of cake.

So if there is another caravan on its way, there’s no point in building a wall to stop them. No caravan of thousands of men, women, and children is going to cross the US border in the middle of the Mojave Desert or the Arizona Plateau. Their destination is a legal port of entry where they can apply for asylym, and those places already have walls. So maybe we can stop burbling on about the wall and instead do something about our asylum process?
