With anxiety over the White House’s Middle East policy mounting in some pro-Israel circles, several Jewish organizational leaders have found themselves in a discomfiting position: criticizing the Obama administration in public while stridently defending the president in private against the most extreme attacks.

It's an upside-down version of what pro-Israel groups usually do: lavishing praise on the U.S. government of the day for sustaining the "unbreakable bond" while making their criticisms known quietly, behind closed doors.

The criticism has come in the form of mostly polite statements and newspaper ads questioning Obama administration pressure on Prime Minister Benjamin Netanyahu's government, particularly regarding building in eastern Jerusalem. Such criticisms are voiced as well in private meetings with administration officials.

The defense comes up in dealings with irate donors and constituents, in phone calls, e-mails, addresses to small Jewish groups, shul talk. The theme of the complaints is consistent, and shocking, said multiple leaders, who all spoke off the record, and reflect the subterranean rumblings about the president heard during the campaign: His sympathy lies with the Muslims, he doesn't care about Israel, he's an anti-Semite.

The Jewish Federations of North America is sufficiently concerned about the phenomenon to have convened a "fly-in" of Jewish organizational leaders to Washington for an as yet unannounced date in May. The leaders will meet with White House, State Department and congressional officials, in part to "to convey concerns about U.S.-Israel relations" -- but also, insiders say, to allay those concerns.

One recent flood of anxious queries followed the Obama administration's announcement earlier this month of its long-awaited nuclear policy. The reality of the policy was a pledge not to threaten with nuclear weapons those nations that provably disavow their nuclear weapons capability. Nations that continued to maintain a threatening nuclear posture, the policy made clear, would still face the prospect of a U.S. nuclear response should they attack the United States or its allies.

Obama named Iran as such a nation.

Yet instead of being reassured, donors and members of national Jewish groups flooded Jewish leaders with anxious queries about a posture that they interpreted as being aimed at embracing a nuclear Iran and forcing Israel to abandon its own reported nuclear capability.

Another persistent -- and unfounded -- rumor has it that Obama removed the phrase "Next Year in Jerusalem" from the White House seder in March.

"Where the **** are they getting this?" asked a senior official at an organization that has been publicly critical of Obama since last summer.

Angst was stoked, too, when Obama spoke last week of peacemaking throughout the world necessitated by the cost of "American blood and treasure" through involvement in conflicts. It didn't help that a New York Times analysis suggested the president had said that the lack of Israeli-Palestinian peace threatened U.S. troops in other parts of the globe -- even though the transcript of Obama's remarks did not bear out any such linkage and other Obama administration officials flatly denied one existed.

Jewish officials said a share of the blame lay with the Obama administration, partly for not adequately reaching out to Jews and to Israel, and partly because of the emergence of what appears to be internecine policy wars.

"The real story of The New York Times story is not that he's changing Israel policy," said another leader of an organization that has not been shy about criticizing the Obama administration. "The real story is, why are officials leaking" misrepresentations of his policy "to The New York Times?"

On the other side, one leader blamed the Netanyahu government for sending mixed signals on how to handle the tensions between Israel and the United States over settlement policy.

"Some are saying quiet is the best answer and others are saying loud noise is the best answer," the Jewish organizational official said.

The official cited reports that Netanyahu personally approved public letters -- from Ronald Lauder, the president of the World Jewish Congress, and Elie Wiesel, the internationally known Holocaust survivor and Nobel Peace laureate -- criticizing Obama's demand for a halt in Jerusalem building.

Despite mounting criticism by some Jewish leaders, polls show that Obama's support among Jews in general remains strong. His backing has dropped from astronomical highs after he was elected, but remains about 10 points stronger than in the general population. Moreover, to the degree that it has eroded, the dissatisfaction with Obama appears to have more to do with unhappiness over his handling of health care and the economy than it does Israel.

Those who are expressing their concerns, however, are among the most active members of the pro-Israel community and help set the tone for the trilateral U.S.-Israel-Jewish leadership ties. Some are acquiring their information from anti-Obama e-mail blasts and consistently partisan critics of Obama.

Richard Baehr, writing in the conservative online magazine The American Thinker, cited The New York Times' misreading of Obama's remarks in arguing that "this president is the greatest threat to the strategic alliance of the U.S. and Israel since the founding of the modern Jewish state in 1948."

McLaughlin & Associates, a GOP polling firm, touted signs last week that Jewish support for Obama was eroding, but the survey questions were premised on shaky assertions. One question posited that Obama would support a unilateral declaration of Palestinian independence, although U.S. officials have consistently said they would oppose such a move. Another suggested that Obama was ready to force Israel to give up the Jewish quarter in Jerusalem's Old City, although there has been no such pressure.

Administration defenders cite signs suggesting that beyond the settlement rhetoric, the relationship is improving: Obama has increased defense cooperation, for instance, and strategic consultations between officials of both nations are more frequent than they have been in a decade.

"Our bond with Israel is unshakable and unbreakable both as it relates to security, as it relates to a common set of values and also as a common strategic vision because the threats to Israel are similar to some of the threats the United States faces," Rahm Emanuel, Obama's chief of staff, said Monday on Bloomberg TV.

Jewish leaders welcome such reassurances but say they are made defensively, and repeatedly call on the Obama administration to become proactive.

Robert Wexler, the former Florida congressman who was Obama's chief Jewish proxy during the election and now heads the Center for Middle East peace, suggested a more proactive posture was in the offing.

"Actions in the next several months will begin to reflect it," he told JTA.

Notably, Emanuel held a behind-closed-doors meeting Tuesday with a group of leading Orthodox rabbis.

Meantime, Jewish leaders are walking a tightrope trying to balance traditional deference to the administration with concerns over the tensions. They also object to what they see as the unwarranted pressure on Netanyahu as opposed to relatively little pressure on the Palestinians to join talks that Israel has embraced with enthusiasm. Israel, they hasten to argue, remains America’s best friend in the region.

Lee Rosenberg, the president of the American Israel Public Affairs Committee, made the Israel-is-our-best-friend case last week at Israel Independence Day celebrations, sharing the stage with Obama's top political adviser, David Axelrod.

"Israel stood by America in spirit and in action after the tragic events of 9-11," Rosenberg said. "As both our great nations fight the same scourge of terrorism and Islamic extremism, it is Israel which serves on the front lines as an outpost of American interests in a dangerous part of the world."

The Wiesel and Lauder letters offered a suggestive contrast over how to handle the tensions.

Wiesel's critique was oblique, not naming Obama, and deferred to U.S. orthodoxy that a final-status agreement must accommodate Palestinian claims to the city.

"What is the solution?" Wiesel asked. "Pressure will not produce a solution. Is there a solution? There must be, there will be."

Lauder, by contrast, directly addressed Obama and suggested that the president was sacrificing Israel to improve relations with the Muslim world.

"The Administration’s desire to improve relations with the Muslim world is well known," said Lauder, an active Republican. "But is friction with Israel part of this new strategy? Is it assumed worsening relations with Israel can improve relations with Muslims?"

One of the Jewish leaders said the contrast was instructive.

"For all intents and purposes, the WJC's relationship with the White House ended last week," he said of the group Lauder heads. "That's not a relationship that pro-Israel groups can afford to have over the next couple of years."

Abraham Foxman of the Anti-Defamation League has publicly criticized the administration on several Israel-related fronts. Still, he said, Jewish leaders have a responsibility to defend the president “when talking to those who accuse him of being an enemy of Israel or a Muslim.”

“For many years, you had a lot of Jews who didn’t vote for President Bush who would say, ‘I don’t like Bush but I love what he's doing on Israel,’” Foxman said.

“Now the paradigm is changing. A lot of Jews are saying, ‘I like Obama, but I don’t like what he is doing on Israel.”

Foxman added that the most frequent question he hears when speaking to Jewish audiences is whether Obama is a friend of Israel.

“I say yes -- but what's wrong is the implementation of what he promised. What's flawed is the strategy, not the goal,” Foxman said.

The ADL leader quickly added that despite promises to learn from past mistakes, the administration’s handling of Israel-related issues is “going from bad to worse."
