Can foreign conflicts reignite prejudice toward historically marginalized groups? In times of war, minorities associated with the state’s enemy are often singled out as a domestic threat. What is less clear, however, is whether a war overseas that does not involve, nor even threaten, a given state will produce similar effects. Since Hamas’ 2023 attack on Israel and Israel’s initial military response, there have been increasing reports of discrimination and violent incidents targeting Jewish citizens of other countries. Do these acts reflect a rise in antisemitism among the general public or just an emboldened antisemitic fringe? Moreover, how does consuming media coverage about the war shape public attitudes towards Jews, both abroad and domestically? To address these questions, we conducted preregistered survey experiments in Bosnia & Herzegovina and Serbia, both of which have small but widely known Jewish minorities. We present survey respondents with a series of newspaper headlines about the Israel/Gaza war, Russia/Ukraine war or a placebo topic. As expected, exposure to the Israel/Gaza headlines increased endorsement of antisemitic stereotypes. However, contrary to expectations, Russia/Ukraine headlines did as well. Yet even as stereotypes increased, attitudes toward prospective Jewish neighbors remained overwhelmingly favorable.
