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.
