Israel’s military response in Gaza to Hamas’s terrorist attack and hostage taking of 7 October 2023 has led to fears of growing antisemitism. Indications of heightened antisemitism include massive spikes in antisemitic incidents and hate crimes around the world and the US, demonstrations and campus unrest, and antisemitic memes on the internet and social media platforms. Questions remain, however, whether public opinion has become increasingly hostile to Jews. The ADL Global 100 reports nearly a doubling in antisemitic sentiment from 2014 to 2024. This paper explores trends in antisemitism using country-level ADL Global 100 data. Results show some countries exhibiting large increases in antisemitism, but not all. For the 2023–2024 comparisons, European nations display relatively stable antisemitic distributions, but Russia shows a large increase. The study also uses American National Election study (ANES) data, both pooled from 1964–2024 and the 2020–2024 panel. The ANES data show a slight drop in warmth to Jews using the feeling thermometer. Demographics do not account for the slight drop, but analysis of the panel data suggests that attitudes toward Israel may account for the decline in warmth.
Jeffrey Е. Cohen (2025) studied this question.
