Andrew Neil of BBC kept asking Labour Party leader Jeremy Corbyn the same question -- over and over.

"Eighty percent of Jews think that you're anti-Semitic," he stressed. "Wouldn't you like to take this opportunity tonight to apologize to the British Jewish community for what's happened?"

Corbyn would not yield: "What I'll say is this -- I am determined that our society will be safe for people of all faiths."

The Daily Express called this late-2019 clash a "horror show." This BBC interview, with surging fears of public anti-Semitism, lingered in headlines as Brits went to the polls. Corbyn's party suffered its worst defeat in nearly a century.

Meanwhile, in America, a wave of anti-Semitic attacks left Jews wondering if it was safe to wear yarmulkes and symbols of their faith while walking the sidewalks of New York City. In suburban Monsey, a machete-waving attacker stabbed five people at a Hasidic rabbi's Hanukkah party. Finally, thousands of New Yorkers marched to show solidarity with the Jewish community.

The NYPD estimates that anti-Semitic crimes rose 26% last year. Anti-Semitic hate crimes in New York, Los Angeles and Chicago are expected to hit an 18-year high, according to research at California State University, San Bernardino. 

No one who watches the news can doubt that "the darkness has returned. It has returned likewise to virtually every country in Europe," argued Rabbi Lord Jonathan Sacks, who led the United Hebrew Congregations of the Commonwealth from 1991-2013. He was knighted by Queen Elizabeth in 2005 and entered the House of Lords.

"That this should have happened within living memory of the Holocaust, after the most systematic attempt ever made … to find a cure for the virus of the world's longest hate -- more than half a century of Holocaust education and anti-racist legislation -- is almost unbelievable. It is particularly traumatic that this has happened in the United States, the country where Jews felt more at home than anywhere else in the Diaspora."

Why now?
