For many Jews, the distress was heightened by connections to friends, relatives or colleagues in Israel, some still missing or unaccounted for on Monday.
Rabbi David Wolpe, a visiting scholar at Harvard Divinity School, described obsessively watching the news in recent days while keeping in constant contact with friends in Israel. “I know any number of people whose kids have been mobilized and who spent nights in safe houses, who’ve lost friends or have had friends kidnapped,” he said.
Like others, he said he feared what lay ahead, and the likelihood that the toll would grow. “As a human being, and as a rabbi, the last thing I want to see is innocents dying for the decisions of their leaders,” he said.
At Brandeis University in Waltham, Mass., a school founded by American Jews, the mood was solemn on Monday, said Ronald Liebowitz, the university’s president, who spent part of the day roaming the campus and talking to students. Many were grieving on behalf of a well-known emeritus professor, Ilan Troen, whose daughter and son-in-law were killed in the attack while protecting their 16-year-old son, who survived.
While he is preparing for the possibility of growing tension between campus groups that hold opposing views on the Israeli-Palestinian conflict, Mr. Liebowitz said he sensed the usual campus debates had been placed on hold.
“Politics, at least here, seem to be set aside for now,” he said, adding: “No one I know is looking at those issues of politics now. They’re looking at the savagery of these attacks.”
