These are interspecies aliens from the planet JoMonDa abandoned in the great border wars in the outer ring deltas. We must not shirk our humanitarian duty to look out for these hapless orphans.
Last time I was down in the south of Mexico a couple of years ago, I picked up a newspaper with the photo of a couple of Guatemalans that had just been apprehended trying to sneak across the border into Mexico.
My Mexican friends told me that these guys were going to spend some time in a badass Campeche lockup before being shipped home. From what I've heard, this recent flood of migrants represent a change in SOP on Mexico's part.
The numbers so far are not huge, but I think that this operation is being run to set precedents and establish procedures for the tsunami that is to come. The tsunami that is to come is a prelude to the war that is to come, and the dems and globalistas mean to import numbers of the needy, pliant, credulous and dependent that will gladly don whatever uniform they'll be conscripted to wear.
