LESBOS, Greece—On Sept. 9, Europe’s largest refugee camp, Moria, on the Greek island of Lesbos burned to the ground, leaving nearly 13,000 people frightened and homeless. But to call Moria a refugee camp is an insult to most well-run refugee camps around the world that do not burn down with such predictable regularity. That this incinerated ghetto was a cornerstone of EU migration policy should prompt an urgent and expansive rethink of how to humanely manage a phenomenon that will continue to grow as new conflicts rage and economies collapse.
