When President Barack Obama steps into the Middle East’s political cauldron this coming week, he won’t be seeking any grand resolution for the region’s vexing problems.His goal will be trying to keep the troubles, from Iran’s suspected pursuit of a nuclear weapon to the bitter discord between Israelis and Palestinians, from boiling over on his watch.Obama arrives in Jerusalem on Wednesday for his first trip to Israel as president. His first priority will be resetting his oft-troubled relationship with now-weakened Israeli Prime Minister Benjamin Netanyahu and evaluating the new coalition government Netanyahu laboriously cobbled together.The president also will look to boost his appeal to a skeptical Israeli public, as well as to frustrated Palestinians."This is not about accomplishing anything now. This is what I call a down payment trip,” said Aaron David Miller, an adviser on Mideast peace to six secretaries of state who is now at the Woodrow Wilson International Center.For much of Obama’s first term, White House officials saw little reason for him to go to the region without a realistic chance for a peace accord between the Israelis and Palestinians. But with the president’s one attempt at a U.S.-brokered deal thwarted in his first term and the two sides even more at odds, the White House has shifted thinking.Officials now see the lowered expectations as a chance to create space for frank conversations between Obama and both sides about what it will take to get back to the negotiating table. The president will use his face-to-face meetings to "persuade both sides to refrain from taking provocative unilateral actions that could be self-defeating,” said Haim Malka, a senior fellow at the Center for Strategic and International Studies.The trip gives Obama the opportunity to meet Netanyahu on his own turf, and that could help ease the tension that has at times defined their relationship.The leaders have tangled over Israeli settlements in the Palestinian territories, and Netanyahu has questioned Obama’s commitment to containing Iran’s nuclear ambitions. Netanyahu also famously lectured the president in front of the media during a 2011 meeting in the Oval Office, and later made no secret of his fondness for Republican challenger Mitt Romney in last year’s presidential campaign.Agencies
