Trump no doubt thought the travel ban would also be “the course of least resistance”—though, unlike 9/11 or the Palmer Raids, there has not been an attack or even a specific threat from any of the seven countries in question. How wrong he was. The resistance to his action has been immediate, spontaneous, and widespread. If this is what measures aimed at foreigners trigger, imagine what will happen if and when he issues an executive order that infringes on any Americans’ rights. The reaction to the executive order may be a sign that Americans have come to realize that we are a nation of immigrants. More likely, it reflects the depth and breadth of concern about Trump’s proclivity to abuse the office—and our rights—generally.
