Israeli American scholar Omer Bartov, one of the world's leading experts on the Holocaust, says Israel's brutal assault on the Gaza Strip is at risk of becoming a genocide. "There is an indication that there are war crimes happening in Gaza, potentially also crimes against humanity," says Bartov. "If this so-called operation continues, that may become ethnic cleansing … and that may become genocide."

The monthlong air and ground war has killed more than 11,000 Palestinians in the besieged enclave, a majority of them women and children. Israel has also severely limited the movement of food, water, fuel, medicine and other essentials into Gaza. Bartov says the disproportionate killing of civilians by Israel, as well as dehumanizing statements by Israeli leaders and suggestions of mass expulsion, are of grave concern. He recently joined hundreds of lawyers and academics in signing an open letter warning about Israel's violations of international law in Gaza.
