I know how ugly it can get. I sat in the Oval Office as Donald Trump fantasized about replicating North Korea’s demilitarized zone on the U.S. southern border, replete with land mines, barbed wire, electric fences, and armed guards. Trump described in graphic detail the sharp, flesh-piercing spikes he wanted installed on the border wall, designed to maim climbers so bloodily that other migrants would be scared to follow suit. He mused about U.S. soldiers firing on civilians, knowing that if they blew the legs out from underneath pregnant mothers, it would keep them from reaching the border.
