This month, the left-leaning daily Haaretz highlighted internal discussions in the ministry about what artistic works might be considered “politically undesirable” for high-school students. Among the criteria, the newspaper said, were whether artists would perform in West Bank settlements and declare loyalty to the state and to the national anthem, something that is particularly problematic for Israel’s Arab citizens.Internal discussions are not policy, but even this report drew stinging responses, with Oded Kotler, a prominent Israeli actor and director, comparing Israel to the Soviet Union and telling Israel Radio, “There’s a real culture war underway here, but the war from that side of the political map is a harbinger of zealotry, darkness and coercion.”Mr. Kotler infuriated the government and the political right last summer when he compared its supporters to “cud-chewing cattle.” That was in response to Ms. Regev’s effort to freeze state funding for an Arab theater in Haifa because of a play about a Palestinian prisoner who murders an Israeli soldier. The production, “Parallel Time,” had enraged the right and Mr. Bennett banned school trips to see it.
