WASHINGTON –In the course of just a few weeks, it may seem that many in the Bush administration and in Israel stopped on a dime, turned and began moving swiftly toward the notion of reviving Israeli-Palestinian peace negotiations.

But lagging behind are many leaders of the organized American Jewish community, still skeptical of the new Palestinian leadership and harboring vivid memories of a similar track a decade earlier that not only failed but turned into 2-1/2 years of terror and violence.

Publicly, most Jewish organizations support the "road map" for Israeli-Palestinian peace that President Bush has been promoting in his Middle East travels this week and at his summit with Israeli Prime Minister Ariel Sharon and his new Palestinian counterpart, Mahmoud Abbas.

But privately, there is much skepticism about what will transpire in the coming weeks and months, with fears that Israel will be forced to make too many concessions or that Palestinians will get a state without first cracking down on terrorism.

The goal, many say, is to make these concerns heard quietly, without standing in the way of progress.

Mainstream Jewish leaders who have reservations say they are not worried that they will be viewed as impediments for peace. Instead, they say they are on the same wavelength as Israel's government, supporting the process — hesitantly.

"The center, I am convinced, has already shifted in support for Sharon and Bush," said Abraham Foxman, national director of the Anti-Defamation League.

"If it's good enough for Sharon and good enough for Israelis, then the American Jewish community will embrace it."

But to some, supporting the Israeli government means more than backing what is said publicly.

Some Jewish leaders feel it is up to them to say what many in Israel, including Sharon, are thinking but are not saying. They say political pressure may have forced Sharon to back something he truly does not believe in, and it is the Jewish community's job to balance the support Israel is expressing with voices of caution.

This is not the first time the organized American Jewish community faces the prospect of suddenly embracing a peace process after years of echoing hardline Israeli positions with respect to the Palestinians. When the Oslo process evolved in the mid-1990s, some prominent Jewish organizations, including the umbrella Conference of Presidents of Major American Jewish Organizations, were accused of not fully backing the process the Israeli government had adopted.

Indeed, in 1995, then-Israeli Prime Minister Yitzhak Rabin chastised Jewish leaders for not getting on board and supporting the Oslo peace process.

The Oslo process "was very difficult for the Jewish community to digest," said Martin Raffel, associate executive director of the Jewish Council for Public Affairs.

"Our mistrust in Yasser Arafat proved to be well-placed."

This time around, some Jewish leaders say they are once again skeptical.

But the difference is, some say, that skepticism is shared by Israel.

"Everybody is hesitant," said Malcolm Hoenlein, executive vice chairman of the Conference of Presidents. "A lot of people have reservations because they see this as a very risky approach."

Hoenlein and others say the 14 reservations about the road map that Israel submitted to the United States last month mirror the concerns they have been expressing for months, and there is still strong concern that Arafat, the Palestinian Authority president, retains much of the control of the security system in the West Bank and Gaza.

There's a decade's worth of experience that makes American Jews fear the worst.

"If it's hard for the community to be on board, it's for good reason," said Morris Amitay, a former executive director of the American Israel Public Affairs Committee. "I don't think the Jewish community will be that much ahead or behind Congress and public opinion."

That worries some more dovish Jewish groups, who fear Jewish leaders may be reluctant to embrace a new process, when the last one burned Israel.

Lewis Roth, assistant executive director of Americans for Peace Now, fears that Jewish groups, while technically on board, will not expend any political capital on supporting — and pushing — the peace process.

The question, others say, is whether Abbas and the Palestinians will follow through where they have not in the past.

If progress is made by the Palestinians, with terrorism especially coming to an end, there would be almost universal support among American Jews for a revived peace process, they say.

Even hawkish groups like the Zionist Organization of America say they will "openly and publicly support negotiations" if the environment is right, said the group's national president, Morton Klein.

He said they would need to see Palestinian arrests of terrorists and other requirements met before they support the process.

Indeed, several Jewish leaders said they will be working in the weeks and months ahead to ensure that Palestinians and other partners are keeping the commitments stressed in the road map because they fear the main problem with Oslo was that Palestinian compliance was not enforced.

"The role for the American Jewish community is to be skeptical and watch and move in when the Arabs are not fulfilling their commitments," Amitay said.

Also on the agenda is setting the scene to entice the Palestinians to fulfill those commitments.

AIPAC, the pro-Israel lobby, last month pushed for a provision in the State Department Authorization Act that would give substantial U.S. assistance to a Palestinian state, once it achieved a thorough peace.

Some Jewish leaders said the provision, sponsored by U.S. Reps. Henry Hyde (R-Ill.) and Tom Lantos (D-San Mateo), the leaders of the House International Relations Committee, sent a signal that the new state would have American Jewish support.

For now, many American Jewish groups say they will take their cues from the Israeli government.

"Some of us sometimes lose sight of the fact that it's their decision," Foxman said. "It's not our role to push them or to hold them back."
