On Tuesday, Gideon Sa’ar, the highest-ranked member of the Likud party after the prime minister, resigned from the Knesset in order to form a new political party that can challenge Netanyahu. By doing so, he both unsettles the shaky governing coalition and joins the long list of Netanyahu’s allies-turned-enemies. Haviv Rettig Gur explains the implications:

Last month, David Miller, a sociology professor at Bristol University, attracted the attention of the Anglo-Jewish press with a rant about the supposed danger posed to civic and campus life by Zionists. Such rhetoric is nothing new for Miller, who has argued—in his academic work as well as in other contexts—that campus Jewish societies are in the employ of a nefarious “Israel lobby,” and that interfaith activities involving Jewish and Muslim communities are “a Trojan horse for normalizing Zionism.” He is likewise convinced that Bashar al-Assad’s mass slaughter of his own people is a hoax perpetrated by a similarly nefarious conspiracy. Unsurprisingly, David Hirsh observes, Miller also believes complaints of anti-Semitism are Isra made in bad faith.
