Emanuelle Sippy, a 20-year-old junior at Princeton University who heads the campus’s Alliance of Jewish Progressives, came to believe in recent years that Israel is an apartheid state guilty of committing human-rights abuses. The war in Gaza has reinforced her views, and she has responded by participating in vigils, walkouts and other actions demanding a cease-fire.Sippy’s father, David Wirtschafter—a Reform rabbi in Lexington, Ky., who attended rabbinical school in Jerusalem—aches when he hears some of her harshest criticisms of Israel. And Sippy’s grandmother, Carol Wirtschafter, who lived with her husband and children in Jerusalem during the 1973 Yom Kippur War, laments that Sippy has lost hope for the country.Copyright ©2023 Dow Jones & Company, Inc.
