It is easy to get the impression the GOP-led House of Representatives is trying to out-Likud the Likud. The reaction on Capitol Hill to the Palestinians’ desire for United Nations membership may be more strident than that of the Israeli government.

But it’s hard to tell because the Israelis are delivering a very mixed message.

Congressional staffers reported Israeli diplomats were this week privately telling them Prime Minister Benjamin Netanyahu wants all U.S. aid cut off unless the Palestinians drop their U.N. bid.

That contradicts public messages from the Israeli leadership suggesting a “tempered” response, said a House source, and almost plaintive public calls to resume peace talks.

The Israeli Foreign Ministry seemed to be taking opposing positions on its website this week. On one page was a speech by Deputy Foreign Minister Danny Ayalon warning the Palestine Donors Conference in New York that the Palestinian U.N. initiative could “severely and irreparably” compromise “future assistance and cooperation” with the Palestinian Authority, while on another was a report submitted to the same meeting saying, “Israel calls for ongoing international support for the P.A. budget and development projects.”

On Capitol Hill, Democrats are afraid of being out-Israeled by Republicans, and many are trying to match the stridency of the majority party.

Several Republican members of Congress, led by tea partier Joe Walsh (R-Ill.), introduced a resolution “supporting Israel’s right to annex Judea and Samaria” if the P.A. unilaterally declares statehood — something only Israeli ultra-nationalists are pushing. Ohio Republican Steve Chabot wants to withhold U.S. dues to the United Nations. Others are proposing closing the PLO Washington office.

In June, both the House and Senate passed a nonbinding resolution with overwhelming bipartisan majorities threatening to restrict U.S. aid if the Palestinians persisted in their U.N. strategy. Fifty-eight Democrats sent their own letter to European leaders asking them to pressure the Palestinians to change their minds.

Few on Capitol Hill believe Mahmoud Abbas when he says his U.N. strategy is designed to bring Israel back to the negotiating table. He could have done that any time in the year since he walked away from the peace table. All he has to do is test whether Netanyahuis bluffing   when he says

he is ready for unconditional talks.

It’s hard to take Abbas seriously when he bypasses so many opportunities. He has a U.S. president, once one of his strongest supporters, pleading with him to return to the peace table. He seems not to care that has

done much damage to that critical relationship.

There’s more involved than foreign policy. Here in Washington, the debate is really less about Mideast peace and more about domestic politics.

Republicans are determined to make support for Israel a political wedge issue in the 2012 campaigns, and they took great encouragement from the race in New York’s 9th Congressional district last week when a Roman Catholic Republican beat an Orthodox Jewish Democrat in arguably the most Orthodox Jewish district in the country. It is inaccurate to call the election a referendum on President Barack Obama’s handling of the Israel issue — but that’s how many choose to interpret it.

Partisan Republicans allied with the Israeli far right are hammering home their theme that they are Israel’s best friends and Democrats, especially Obama, are unreliable at best.

That has many Democrats worried, especially the fundraisers who fear longtime contributors will stay on the sidelines or, worse, give to Republicans, whose battle cry is “We love Israel more.”

It’s about money, not votes. The current crop of GOP presidential contenders is running so far to the right that there is little hope any can attract significant numbers of Jewish voters.

The target audience for the fear and smear anti-Obama campaign is pro-Israel activists with deep pockets.

The main victim will be the historic bipartisan consensus if support of Israel is allowed to become a political wedge issue. The one suffering most will be Israel as the focus shifts from making friends in both parties to pursuing purely partisan aims.

Rep. Ileana Ros-Lehtinen (R-Fla.), chair of the House Foreign Affairs Committee, held hearings last week to showcase her threat to cut off all aid to the P.A. She was surprised when a star witness, Elliot Abrams, George W. Bush’s top White House Middle East adviser, warned a cutoff could lead to the collapse of the P.A. and would not be in the interest of the United States or Israel but “might actually benefit Hamas and other terrorist groups.”

Hill staffers report Israeli diplomats have told them that the word from Netanyahu is that unless the Palestinians change course, all U.S. aid should be halted. “Bibi knows how to use Congress, and he wants to use us to scare them,” said one aide who’d met with senior embassy representatives.

One ploy being considered by Ros-Lehtinen, according to a committee source, is to require any release of aid to the P.A. to have a signed presidential national security waiver. That will let the Republicans say they cut off the aid and give them one more target for attacks when Obama invokes the waiver.

“What worries people up here is that if we withhold some or all of the aid, when the time comes to release funds, will Netanyahu provide the political cover needed or just leave us twisting in the wind,” the source said.

As Netanyahu gives the U.N. his conciliatory message of readiness for peace, his cheering section on Capitol Hill will be hammering out a different tune.
