Israel lobby presses Congress to soften Obama's tough stance on Netanyahu

America's main pro-Israel lobby group is mobilising members of Congress to pressure the White House over its bitter public confrontation with Binyamin Netanyahu, the Israeli prime minister.

The move, by the American Israel Public Affairs Committee (Aipac), appears aimed at exploiting differences in the Obama administration as it decides how to use the crisis around settlement building in Jerusalem to press Israel towards concessions to kickstart peace negotiations.

Aipac has persuaded more than three-quarters of the members of the US House of Representatives to sign a letter calling for an end to public criticism of Israel and urging the US to "reinforce" its relationship with the Jewish state.

The open letter, which has been circulating among members of Congress for the last week, says that while it is recognised that there will be differences between the two countries, they should be kept behind closed doors. "Our view is that such differences are best resolved quietly, in trust and confidence," it says.

The public differences, and revelations of Obama's private snubs of Netanyahu at the White House last week, have proved embarrassing to the Israeli leader at home, where he has been accused of undermining Israel's most important relationship.

Signatories to Aipac's letter include Steny Hoyer, the Democrat majority leader, and Eric Cantor, the Republican whip. The wording is similar to an email Aipac sent out during Netanyahu's visit, describing Obama's criticisms of the Israeli government as "a matter of serious concern" and calling on the US administration "to take immediate steps to defuse the tension with the Jewish state".

But while Aipac has for years influenced US policy on Israel, by targeting members of Congress who criticise the Jewish state, it may no longer have the same impact.

Robert Malley, a former special assistant to President Bill Clinton for Arab-Israeli affairs, said the administration's decision to take a once routine disagreement over settlement construction in East Jerusalem and turn it in to a confrontation is a reflection of the determination in the White House.
