But criticism of Israel is not inherently free of anti-Semitism, either — a point that I wish more critics of Israel would acknowledge. Here are a few such forms of anti-Semitism:

- Calls for the elimination of the Jewish state that are suspiciously silent about the need to eliminate other religious states. Questioning Israel’s right to exist often falls into this category.

- The old trope that Jews have secret powers to control other people. Ilhan Omar, the Minnesota congresswoman, dabbled in this sort of conspiracy when she tweeted in 2012 that Israel had “hypnotized the world” to keep people from seeing its “evil doings.”

- The related trope that Jews use their money to control people. An example: A London mural that depicted hooknosed bankers running the world— which Jeremy Corbyn, the leader of Britain’s Labour Party, initially defended. Another example: Omar’s claim over the weekend that members of Congress support Israel because of money they receive from pro-Israel lobbyists. “It’s all about the Benjamins,” she tweeted.

Yes, the tweet was bad.
