From Cambridge to Los Angeles and at dozens of schools in between, campuses are roiled by protest against American financial and military support for Israel’s war in Gaza—and by university actions, including mass arrests, to suppress the protesters. There hasn’t been a college protest movement as widespread since the Vietnam War. Apart from the violence in the Middle East, the protests also engage crucial issues of speech and academic freedom in the context of America’s culture war. David Remnick looks at the turmoil and its reverberations through the lens of one campus, Harvard University, where much of the furor began. He speaks with a protester whose statement justifying the October 7th Hamas attack became a political flashpoint; two student journalists who covered the resignation of the university’s president Claudine Gay; the law-school professor Randall Kennedy; and the former Harvard president Lawrence Summers.
