After an hour and a half of trying to soften an increasingly furious—and personal— debate over Palestinian membership in the United Nations on Tuesday, moderator John Donvan gave up and wearily asked his panelists for closing statements. Aaron David Miller started off. “I realize in the last 90 minutes that perhaps one of the most astute things I’ve done, the best decisions I’ve made, was to leave the Arab-Israeli negotiating table,” he quipped. The audience laughed. Onstage, the rest of the panelists looked pained.
