A day after Israel’s Cabinet announced that it would consider making a loyalty oath mandatory for non-Jewish immigrants, the question put to The Israel Project’s president and founder was simple enough.

“How did your organization react?” Natasha Mozgovoya, the Washington correspondent for Israel’s daily Haaretz, asked Jennifer Laszlo Mizrahi at a news conference last week announcing an expansion of The Israel Project’s activities.

“We didn’t put out a press release” was all Mizrahi would say at the time.

The story, making headlines in Israel and around the world, redounded into emptiness in the mainstream American Jewish establishment even after the Cabinet approved the oath in a vote Sunday.

The silence reflected a reluctance to criticize Israel at a delicate period in its negotiations with the Palestinians, and as Israel gears up for what could become intensified confrontation with Iran.

The loyalty oath, which must be approved by the full Knesset to become law, would require non-Jewish immigrants to swear allegiance to Israel as a “Jewish and democratic state.” It was a longtime condition of participation in the governing coalition by Yisrael Beitenu, the party that helped crown Benjamin Netanyahu prime minister in early 2009 by joining his Likud Party in the government.

A measure that has drawn sharp criticism on the Israeli left, and from some figures on the political right and center, was supported by 22 Cabinet members and opposed by eight -- Labor’s five ministers and three from Likud.

In America, Mizrahi's Israel Project was one of the few organizations other than solidly left-wing ones willing to say anything on the record. On Monday, the Israel Project did put out a release -- a straightforward news story conveying the opinions of both sides on the issue, without judgment as to the merits of the proposed law. Most major centrist groups, including those that lean toward liberal, even kept their refusal to comment off the record.

“The timing is not right,” one official said, referring to the diplomatic impasse in the Middle East.

Others simply declared that they were not prepared to deal with the issue.

The American Jewish Committee said its staff was busy analyzing its latest poll of Jewish voters, and that it might have a statement later this week. The Anti-Defamation League did not address the content of the oath but said it should extend to all new immigrants, Jews and non-Jews.

Groups on the American Jewish left denounced the proposed law in the same strong terms used by their Israeli counterparts. J Street and the New Israel Fund even cited prominent Israelis, like Intelligence Minister Dan Meridor of Likud, in opposing the oath.

“The proposal would harm relations with Israel's Arabs and damage the country's international reputation,” NIF quoted Meridor as saying in its action alert. “Act now to stand up for Israel and its democratic future,” the alert said, urging supporters to contact Netanyahu’s office directly.

The law’s defenders frame it as an appropriate and effective way to deal with efforts to delegitimize Israel.

“Currently, Israel faces the greatest delegitimization campaign of any nation,” Deputy Foreign Minister Danny Ayalon, a member of Yisrael Beitenu, wrote in The Jerusalem Post. “One of the main targets is its national character. Unfortunately, too many Israeli Jews have internalized this assault and have either forgotten, misunderstood or are actively working against the raison d’etre of the re-establishment of Israel.”

What sticks in the craw of opponents is making loyalty to the Jewish state a specific attribute requiring the fealty of non-Jews. Ayalon and others have defended the oath as not differing from the U.S. Pledge of Allegiance required of new citizens. The pledge, however, does not defer to any cultural, religious or ethnic designation.

“It is one thing to require adherence to the law,” Hagai Elad, who directs the NIF-backed Association for Civil Rights in Israel, wrote to supporters. “It is another altogether to demand that free individuals in a democracy sign on to a specific ideology or identity -- and specifically one with particular religious content."

Tzipi Livni, the leader of the opposition Kadima Party, depicted the proposed law as a blunt instrument.

“This law does not contribute anything -- the opposite is true,” The Jerusalem Post quoted her as saying. “It will cause internal conflicts. This is a bad proposed law that does not protect Israel as the Jewish national home, and even harms it."

The ADL’s concern -- that the law’s main fault was in its discriminatory application to non-Jewish immigrants only -- also was reflected at the Cabinet meeting, where Yaakov Neeman proposed an amendment to make it a requirement for every immigrant, regardless of religion. It did not pass.

Ayalon said Jewish immigrants were entitled to the assumption of loyalty.

“The pledge becomes unnecessary for those who join us by virtue of their national and historic ties to our land and people,” he wrote in his Op-Ed. “The Jewish state was created to deal specifically with the issue of the Jewish people, and the return of any Jew to his or her land is the fulfillment of this principle.”
