This is relatively easy to explain if you accept that the statistics in this article relate to anti-israel sentiment rather than antisemitism per se. The truth is that the Israeli government and the people of Israel have moved to the right while the government even courts fascists in Europe and includes fascists in the Knesset.

Meanwhile young American Jews are increasingly distancing themselves from Israel and taking up the cause of the Palestinians. The ADL even recognises this in its analysis if not in its figures. The fact that Jews and Muslims can work together in calling for an end to the Israeli genocide while openly expressing their religion is slowly separating the antisemitic myth of Zionism from actual Jew hatred which consistently remains fairly low among liberal democracies.
