No, the world is not coming to an end. All Trump did was lay out a plan to enforce the border. He didn’t advocate that we use snipers, sharpshooters, or land mines to stop unwary illegals and their DACA-bound kids.
He might as well have.
Instead we got a border wall, which is a pretty benign solution to a very big problem that a fading number of conservatives being criticized as Trump’s base still want to put a stop to.
