JERUSALEM (AFP) - US Secretary of State Condoleezza Rice was left shame-faced after President George W Bush ordered her to abstain in a key UN vote on the Gaza war, Israeli Prime Minister Ehud Olmert said on Monday. "She was left shamed. A resolution that she prepared and arranged, and in the end she did not vote in favour," Olmert said in a speech in the southern town of Ashkelon. The UN Security Council passed a resolution last Thursday calling for an immediate ceasefire in the three-week-old conflict in the Gaza Strip and an Israeli withdrawal from Gaza where hundreds have been killed. Fourteen of the council's 15 members voted in favour of the resolution, which was later rejected by both Israel and Hamas. The United States, Israel's main ally, had initially been expected to voted in line with the other 14 but Rice later became the sole abstention. "In the night between Thursday and Friday, when the secretary of state wanted to lead the vote on a ceasefire at the Security Council, we did not want her to vote in favour," Olmert said "I said 'get me President Bush on the phone'. They said he was in the middle of giving a speech in Philadelphia. I said I didn't care. 'I need to talk to him now'. He got off the podium and spoke to me. "I told him the United States could not vote in favour. It cannot vote in favour of such a resolution. He immediately called the secretary of state and told her not to vote in favour." Bush has consistently placed the blame for the conflict on Hamas, telling reporters on Monday that while he wanted to see a "sustainable ceasefire" in Gaza, it was up to Hamas to choose to end its rocket fire on Israel. Meanwhile, American Jews are divided over the Israeli military offensive against Hamas in the Gaza Strip, which is being vigorously denounced by an increasingly active progressive Jewish movement. The war has sown divisions among Jews here, according to Ori Nir, spokesman for the US branch of the Israeli pacifist movement "Peace Now," long overshadowed by the America-Israel Public Affairs Committee (AIPAC). "Many American Jews view this as a legitimate war," Nir said. "There are however people who are very uncomfortable with the way in which it was carried out and with extend to which diplomatic means were not exhausted ... to prevent this war," he added. J Street circulated a petition calling for an immediate ceasefire in the Gaza Strip just days after Israel's December 27 launch of massive air strikes " at a time when US Secretary of State Condoleezza Rice balked at such calls. "We reiterate that J Street is deeply committed to Israel, its security and the safety of its citizens," the group's director Jeremy Ben-Ami said on the J Street website. "However, as Americans and as friends and supporters of Israel, we do not believe the continuation of the present military operation is in the best interests of either the United States or Israel," he added. He pointed to anti-Israeli demonstrations in Iraq and Afghanistan, where tens of thousands of US soldiers are deployed. "Demonstrations throughout the Middle East and the Muslim world indicate that this week's events are only further damaging America's image, interests and relationships around the world," Ben-Ami argued. Another sign that progressive Jews are gaining ground in the United States is that Walt is today one of the authors that the respected Foreign Policy magazine has chosen to launch a series of blogs on US diplomacy.
