I was quite dismayed to read Mellissa Langsam Braunstein’s column “Zahra Billoo Criticizes ‘Polite Zionists; ’ADL Responds” in the December 16 issue of The Jewish Link. She says the Anti-Defamation League’s CEO Jonathan Greenblatt deserves credit for tweeting CAIR (Council on American Islamic Relations) to condemn their antisemitic activity in the San Francisco Bay Area. This is the same Jonathan Greenblatt who in 2016, in a fit of pique at Donald Trump’s threat to close the border to some, mostly Islamic, countries, famously vowed, “I will register as a Muslim.”

Mr. Greenblatt should know that mixing personal political animus with his obligation to lead a major international Jewish organization in a time of an alarming increase in global antisemitism can unleash forces with unintentional consequences. It is the height of irony that he did this by throwing in his lot with the likes of avowed Muslim antisemites like “the Squad,” who make a mockery of the title “Anti-Defamation” by publicly defaming everything Jewish and Israeli.

Before I start praising Mr. Greenblatt, I prefer to wait and see if his latest utterances represent a sincere change in his commitment, or merely another swing in the pendulum of his political views.
