“As the conflict between Israel and Hamas rages for a fifth day, many Jews around the world face a familiar threat: a surge in antisemitism. From New York to London, St. Louis to Sydney, Jewish communities are grappling with hate and bigotry that often flare up whenever the Middle East erupts. "It's just a sad fact that whenever conflict arises between Israel and the Palestinians, Jews in all parts of the world will suffer some level of hate violence," said Heidi Beirich, co-founder of Global Project Against Hate and Extremism. Israel plunged into a bloody nightmare Saturday when Hamas militants unleashed a surprise onslaught, killing at least 1,000 Israelis, wounding more than 2,000, and taking some 150 as hostages. Brian Levin, a prominent extremism researcher and professor emeritus at California State University, San Bernardino, said the carnage amounted to "the worst single-day slaughter of Jews since the Holocaust." U.S. President Joe Biden condemned the attack as "an act of sheer evil." Israel's retaliatory airstrikes against targets in Gaza have been equally deadly, killing at least 1,100 Palestinians and leaving more than 5,000 others wounded, according to the Gaza Ministry of Health.”
