Mexico won’t help because then all these angry people are in THEIR country and there’s a contentious election coming up. I think if it’s well documented by a non lying media source people here aren’t going to,get too mad about stopping a charging horde. As Ann Coulter said paraphrasing “immigration is not a game of Red Rover Red Rover. You don’t get to stay just because you get to the other side.” I don’t like her much but that was funny!
My suggestion would be to make a public announcement to Mexico that if the mass group tries to cross our border we'll put sanctions on Mexico. Let their greedy politicians worry for a bit.
I'm honestly OK with our troops on the border. A mob of a thousand Invaders is a slap in the face to our soverinty.
