Before he announced his vice presidential pick on Saturday, US Sen. Barack Obama said he wanted someone to spar with but who ultimately would be loyal enough to create a comfortable working relationship. No one knew then that he had picked Sen. Joe Biden, 65, but his description fit Biden's relationship with the US Jewish community to a tee. The loquacious Biden, who has served in the Senate since 1973, has sparred frequently with the pro-Israel community and with Israelis, particularly on settlements. But he has a sterling voting record on proIsrael issues, and has as chairman of the Senate Foreign Relations Committee helped shepherd through key pro-Israel legislation. His straightforwardness is considered an asset, even among those supporters who have disagreed with him. "He's open minded, he votes his own conscience," said Gary Erlbaum, a Philadelphia-based real estate developer who is backing the Republican candidate for president, but has supported Biden's Senate campaigns. "I don't always agree with him" - Biden is a staunch critic of the Bush administration's Iraq policy, Erlbaum helped found the pro-Iraq war group Freedom's Watch - but "he does not try to sugarcoat." Biden has been especially sharp in criticizing the US and Israeli failure to support Mahmoud Abbas in 2003, when he was the Palestinian Authority prime minister attempting to establish a power base to challenge thenpresident Yasser Arafat. Abbas was eventually sidelined by Arafat, allowing the Palestinian leader to continue his policies of corruption and stasis until his death in November 2004 - and creating a vacuum ultimately filled in large part by Hamas. "I've had my shouting matches over 25 years, privately, in my office and in the offices of prime ministers," Biden said in a March 2007 interview with the Forward. "I've had disagreements. Israel's a democracy and they make mistakes. But the notion that somehow if Israel just did the right thing [the peace process] would work, I mean that's the premise, give me a break." In that same interview, Biden firmly rejected calls for the United States to distance itself from Israel and assume a more neutral role in brokering Middle East peace talks. "The suffering is real on both sides, but there is a side that can impact on ending it," he said. "The responsibility rests on those who will not acknowledge the right of Israel to exist, will not play fair, will not deal, will not renounce terror." Just two months earlier, Biden took the lead in the Senate in rejecting the Iraq Study Group's assertion that the United States would not be able to achieve its goals in Iraq unless it "deals directly with the ArabIsraeli conflict." "I do not accept the notion of linkage between Iraq and the Arab-Israeli conflict," Biden said during his opening remarks at a January 17, 2007, Senate hearing. "Arab-Israeli peace is worth pursuing vigorously on its own merits, but even if a peace treaty were signed tomorrow, it would not end the civil war in Iraq." Biden's longstanding relationship with the Jewish community should reassure Jews who still feel anxious about Obama, who has deep ties to the Chicago Jewish community but who has been on the national stage barely four years, said Cameron Kerry, brother of US Sen. John Kerry of Massachusetts. "I've seen the enormous respect he commands in the pro-Israel community," said Cameron Kerry, a convert to Judaism and a senior adviser to his brother's 2004 presidential campaign. "He has a well-established record, he knows the issues, and he can talk the talk. He's may be the best goyische surrogate I've seen in the Jewish community," Kerry said of the vice presidential candidate. One of Biden's sons married a Jew family, but his keen interest in the region dates back to his first visit as a US senator, not long before the Yom Kippur. He met Israel's then-prime minister, Golda Meir. He came away from that meeting understanding that "there is this inextricable tie between culture, religion, ethnicity that most people don't fully understand - that is unique and so strong with Jews worldwide," Biden said in an interview with Shalom TV last year, when he launched his own presidential bid. "When I was a young senator, I used to say, 'If I were a Jew I'd be a Zionist.' I am a Zionist. You don't have to be a Jew to be a Zionist.'" Mark Gittenstein, who worked for Biden from 19761989, said no one matched his breadth of knowledge on Israel - not even his Jewish staffers. "He was much more knowledgeable about Israel and problems than I was." Biden has a keen understanding of the Holocaust, partly because of his relationship with Tom Lantos, the late California Democratic congressman who was the only Holocaust survivor elected to the US House of Representatives. Biden hired Lantos as an adviser in the late 1970s, a leap into politics that led the Hungarian-born economist to consider a political career. At a memorial service for Lantos in February, Biden cracked up the somber crowd by recalling how Lantos marveled at his son-in-laws' very Middle American names. "My daughters married Aryans," Biden recalled Lantos as saying. More substantively, his tutoring by Lantos led Biden to take the lead on genocide issues, and he is currently a champion on efforts to isolate Sudan over its massacre of hundreds of thousands of civilians in Darfur. "Any country that engages in genocide forfeits their sovereignty," he said to applause at a National Jewish Democratic Council presidential candidate forum last year. Obama, who has been outspoken in opposing the Iraq war, had considered a number of centrist and conservative Democrats as running mates to balance his own dovishness. Picking Biden, also a war critic, allows Republicans to describe its the Democratic ticket as much of a muchness. Among Republican Jews, that means scoring both men for opposing some of the tougher anti-Iran measures embraced by the Republican presidential candidate, Sen. John McCain, and some Democrats, including Obama's chief primaries rival, Sen. Hillary Rodham Clinton. "With the selection of Senator Joe Biden as Senator Obama's vice president, the Democrats' ticket has now become an even greater gamble for the Jewish community," the Republican Jewish Coalition said in a statement on Saturday, hours after Obama made his announcement. "Biden has failed to recognize the serious threat that Iran poses to Israel and the US and its allies in the Middle East." In response, Ira Forman, the director of the National Jewish Democratic Council, said that focusing on recent differences over nuances regarding Iran policy missed the larger point of Biden's long years of commitment to Israel. "The RJC would criticize the Democratic pick for vice president if it was Ben-Gurion," Forman said. "There is no one you could possibly pick who knows the issues, who is committed to Israel's security and knows Israeli leaders as much as Joe Biden."
