What Next for US Policy on the Middle East?

Israeli Prime Minister Ehud Olmert arrived at the White House today as James Baker's so-called Iraq Study Group has been meeting with the foreign policy team. It's believed that Baker and new Defense Secretary-designate Robert Gates favor negotiations with Iran. British Prime Minister Tony Blair will address the Iraq Study Group tomorrow. Meantime, Democratic leaders want a phased withdrawal from Iraq, and there's pressure from several directions for talks with Syria. All this as the Palestinian factions, Hamas and Fatah, are putting together a unity government. President Bush is embracing advisors who served his father. Will they push diplomacy rather than confrontation? Is there any chance of a weakened US commitment to Israel?
