Not to worry. Im sure Mexico would give us citizenship, health care, the right to vote, paid assistance....

Ive said many times that Mexico and the Central American countries have been nothing but a collective pain in our ass. The people dont like to live there? Fine. Put the military on the southern border and push everyone south until at least the far side of the canal and build the wall there. No need to worry about displaced people. They didnt want to be where they were and if Brazil doesnt want them then they can all go live in the socialist utopia of Venezuela where they will be taken care of. Its a humanitarian thing really. The walk to Venezuela is much shorter than it is to walk here.
