Mamdani, a leading scholar of postcolonial studies and human rights, made the controversial suggestion during a campus panel discussion last week, where he argued that the scale of civilian casualties in Gaza, combined with repeated Israeli restrictions on humanitarian aid access to the enclave, meets the legal threshold for war crimes as defined under the Rome Statute. “The ICC has a mandate to hold perpetrators of mass civilian harm accountable, regardless of their political position or the support they receive from powerful nations,” Mamdani said during the panel, which drew crowds of both pro-Palestinian supporters and pro-Israel protesters on Columbia’s Morningside Heights campus. When asked for his response to Mamdani’s comments during a Tuesday appearance on CNN’s “The Lead with Jake Tapper,” Fetterman did not mince words. “That’s an absolutely outrageous, ridiculous statement,” Fetterman told Tapper. “Mamdani can sit down. Netanyahu is the leader of a sovereign, democratic ally of the United States, and he is leading his nation through an existential crisis after the worst terrorist attack on Jewish people since the Holocaust. We should be standing with Israel’s right to defend itself, not calling for its elected leaders to be arrested by a body that has no legitimate jurisdiction over them.” Fetterman, who has been one of the most vocal pro-Israel Democrats in Congress since the October 7, 2023, Hamas attacks that killed roughly 1,200 people in southern Israel, has previously drawn criticism from progressive groups for his unwavering support of Israeli military policy in Gaza, including his rejection of calls for a permanent ceasefire. The exchange has amplified already fierce tensions across U.S. college campuses and in political circles, as the ICC confirms it is moving forward with its years-long investigation into alleged war crimes committed by both Israeli officials and Hamas militants in the Palestinian territories. The Biden administration has repeatedly stated it opposes any ICC action against Israeli officials, arguing the court does not have jurisdiction over Israel, which is not a signatory to the Rome Statute. Supporters of Fetterman, including leading Jewish advocacy groups, have praised his remarks as a necessary pushback against what they call rising anti-Israel and antisemitic rhetoric in U.S. academic spaces, while progressive and Palestinian rights groups have condemned Fetterman’s comment as a dismissive rejection of international law and the suffering of more than 34,000 Palestinian civilians killed in Gaza since the war began.
