OPINION: The paper of record needs to reflect deeply on how it came to publish anti-Semitic propaganda.

As prejudices go, anti-Semitism can sometimes be hard to pin down, but on Thursday the opinion pages of The New York Times international edition provided a textbook illustration of it.

Except that The Times wasn’t explaining anti-Semitism. It was purveying it.

It did so in the form of a cartoon, provided to the newspaper by a wire service and published directly above an unrelated column by Tom Friedman, in which a guide dog with a prideful countenance and the face of Benjamin Netanyahu leads a blind, fat Donald Trump wearing dark glasses and a black yarmulke. Lest there be any doubt as to the identity of the dog-man, it wears a collar from which hangs a Star of David.

Here was an image that, in another age, might have been published in the pages of Der Stürmer. The Jew in the form of a dog. The small but wily Jew leading the dumb and trusting American. The hated Trump being Judaized with a skullcap. The nominal servant acting as the true master. The cartoon checked so many anti-Semitic boxes that the only thing missing was a dollar sign.

The image also had an obvious political message: Namely, that in the current administration, the United States follows wherever Israel wants to go. This is false — consider Israel’s horrified reaction to Trump’s announcement last year that he intended to withdraw U.S. forces from Syria — but it’s beside the point. There are legitimate ways to criticize Trump’s approach to Israel, in pictures as well as words. But there was nothing legitimate about this cartoon.

So what was it doing in The Times?
